Most typically, photo- z methods have been applied to broadband filter data ( Ilbert et al. 2006; Tanaka et al. 2018; Lee & Chary 2020, and many others). In such cases, redshifts are primarily derived from large-scale features such as the 4000 Å, Balmer, or Lyman breaks if they are present in between the filter passband ranges. Thereby, a redshift accuracy of up to d z≈ 0.03(1 + z) has been achieved. Using narrow-band filters, this limit can be considerably extended by a more precise localisation of the continuum breaks as well as by the possibility of detecting individual spectral lines: JPLUS/SPLUS ( Izquierdo-Villalba et al. 2019), miniJPAS ( Bonoli et al. 2021), and PAU ( Eriksen et al. 2020; Rodriguez et al. 2020).

The last expression p( F | z, T) gives the probability that the measured relative fluxes F correspond to the template T at redshift z. We assume that the probability does not depend on the magnitude m 0. The prior p( z, T | m 0) can be further developed using the product rule Based on the calculated merit values (see lower panel of Fig. 11), we find that the optimal number of selected templates for bright galaxies is 75, although the differences between other number of chosen templates are not that big for number of templates above 50. In this work, we were satisfied with only one set of 75 templates as we mostly use the magnitude cut of r< 22 mag. But if larger sets of observations should become available in the future, it might be viable to construct different template selections for each brightness range. In a Bayesian framework, the problem of photo- z estimation can be posed as finding the probability of a galaxy having red-shift z given the observational data and some prior information ( Benítez 2000).

For characterising the brightness of the sources and applying luminosity cuts we have used the r-band MAG_AUTO magnitudes. The specific luminosity cut values are described in the text. MilkTopz - 6 x 100% LeakProof, Airtight, Reusable Silicone Milk Bottle Tops for UK 1 Pint Milk Bottles x 6 (Multi Colour) - BOTTLES NOT INCLUDED: Fab product to keep milk fresh In particular, an important J-PAS-specific improvement in TOPz is the possibility to take into account the dependence of the central wavelengths of the filter transmission bands on the incident angle of the light path ( Benítez et al. 2014). This dependence means that each galaxy in each filter is observed through a slightly different passband depending on the physical position of the galaxy’s image on the surface of the filter during an exposure. As only the average passband of each filter of J-PAS is provided at the moment, taking such passband shifts into account would improve the match between synthetic and J-PAS photometry. Currently, this information is lost during the combination of different exposures into ‘tiles’, but can be taken into account with the main J-PAS data releases. For more detailed analysis on how we expect the results to improve, see Appendix A. All of the previous results and plots were shown for sources with r< 22 mag. From the observational perspective, the brighter the galaxies are, the less noisy the observations become and the easier it is to estimate photometric redshifts. The ratio of TOPz photo- z estimations reaching the J-PAS target accuracy depending on the depth of the observations can be seen in the upper panel of Fig. 19. As expected, the photo- z accuracy falls when taking more fainter galaxies into account. As discussed in Sect. 6.1.1, fainter galaxies would benefit from a smaller set of templates.Based on this probability formula, the price of uncut red topaz 1,259 and the price of red topaz 1,470, the minimum Crafting level to breakeven or better when cutting red topaz is 85. The general idea of Bayesian photo- z codes is to calculate the redshift likelihood of a galaxy and estimate the ‘best guess’ redshift from the respective probability density function (PDF). This is illustrated in Fig. 2 using an example of an actual galaxy from the miniJPAS survey. Typically, the redshift value corresponding to the highest PDF value is given as the ‘best guess’ photometric redshift of the galaxy (designated z_ml1d in TOPz). Another possibility is to find the redshift with the highest likelihood value among all the given templates (z_ml2d in TOPz). As explained in Sect. 5, photometric redshift estimation may depend on the set of templates used for approximating the observed spectral distribution of the galaxies. Consider the example of the best-matching template fitted to the photometry of an r = 20.6 galaxy, presented in Fig. 10. On the upper panel, the blue line and squares represent the template spectrum and the corresponding synthetic photometry, respectively, and the orange circles are the observed fluxes together with error estimates in each of the 54 narrow-band filters. Although the photometric errors are relatively large and the scatter of the observations even exceed these errors, we can quite accurately detect the major emission lines. The lower panel shows the marginalised PDF that is produced by our final template set. The PDF peak (z_ml1d) as well as the z_w1d redshift estimation (dashed blue line) are somewhat overestimated. Nevertheless, the photometric redshift is more accurate than the J-PAS target goal of d z/(l + z) < 0.003. Theoretically, machine-learning algorithms are capable of using all the information available in the data and should thus yield maximal possible accuracy. In addition, machine-learning algorithms tend to be faster than template-based ones. However, their performance generally depends on the size and quality of the training set, which becomes problematic at higher redshifts, where an unbiased comprehensive observational data set is hard to obtain; thus machine-learning algorithms are generally outperformed by template-based methods in this regime ( Hildebrandt et al. 2010). In addition, template-based methods have another advantage in that they may simultaneously be used to derive a range of physical properties of galaxies via spectral energy distribution (SED) fitting ( Walcher et al. 2011; Díaz-García et al. 2015, 2019; Battisti et al. 2019; González Delgado et al. 2021).

The impact on the redshift estimation of separating the training and validation subsets can be seen in Fig. 17. We ran the TOPz workflow with three different training set sizes and ten randomly selected training sets were generated for each size. It can be seen that even when using as few as 50% of the miniJPAS catalogue with r< 22 mag for training (i.e. 994 galaxies), we achieve the same fraction of galaxies with d z< 0.003 (blue points) than when using the full miniJPAS catalogue for both training and validating. The same holds true for the σNMAD values (green points). When we increase the training size, the mean values for these characteristics remain almost the same while the variance grows. This is to be expected, as the number of galaxies in the validation sets keep getting smaller and thus the estimates become more affected by the randomness of the subset selection. It can also be seen that no bias is introduced when we increase the number of galaxies in the training subset. Therefore, we can be confident that using the same catalogue for both training and validating the photo- z estimates does not bias the final results.

Globaltopz UK Ltd are always monitoring new trends and product development, while keeping a close eye on the price-quality ratio, to ensure that our products fit today's trends and budgets. Super-sharp photos often pop off the screen with more impact and emotion, so you can often make your photos more powerful by increasing sharpness. However, people are also very sensitive to “unnaturally sharp” photos with haloing and fringing caused by traditional sharpening. Sharpen AI is an intelligent image sharpener specifically trained to give your photos that extra pop while remaining natural.

The results improve progressively when we use the full base template set (blue), enable photometric corrections (orange), apply the reduced template selection (green), and finally enable priors along with the previous steps (red). The grey line shows the photo- z estimations from miniJPAS database and the dashed vertical line marks the target accuracy of J-PAS redshifts. Every added step increases the number of galaxies achieving J-PAS photo- z target accuracy with the biggest improvement coming from implementing the photometric corrections (see Sect. 5.3). Overall, TOPz results are on par with previous miniJPAS photo- z estimations showing the accuracy that template-based photometric redshift methods can reach given the quality of the miniJPAS photometry. Different TOPz redshift estimators (maximum likelihood z_ml1d and weighted z_w1d) yield a similar dependency on source magnitude (see Fig. 19). At the bright end, the object density is low and the scatter in estimators is caused by statistical errors. The weighted estimator is slightly better up to 21 mag and becomes equal to other estimators when taking fainter galaxies into account. The dashed lines in the upper panel of Fig. 19 show the corresponding outlier fraction. As expected, this fraction increases for fainter sources and no real variation in different photo- z estimators can be seen. The accuracy of Hernán-Caballero et al. (2021) photo- z results (presented with grey) is somewhat worse than TOPz for brighter galaxies whereas the accuracy becomes equal for the full catalogue. The differences between Hernán-Caballero et al. (2021) and TOPz results on the brighter end may be caused by different optimisation of templates or other choices in the configuration. However, a detailed analysis of these differences is meaningless given the small size of the galaxy sample and a more thorough assessment have to wait until more data from the full J-PAS survey become available.

In Sect. 5.2, we noted that ~22% of the galaxies in the test catalogue fall outside the colour region that our templates cover. We also noted that these galaxies are fainter on average, having a median brightness of r = 21.57 mag compared to r = 21.21 mag of those galaxies that are inside the region. We find that at a fixed brightness level, the number of galaxies that reach the J-PAS accuracy goal is similar between galaxies outside the colour region and the remaining galaxies. This shows that, although the broadband colours of the templates are somewhat more restricted than those of the observed galaxies, the templates are accurate enough to yield reliable redshift estimates from the full J-PAS filter set. The most probable explanation is that the accuracy of photo- z for fainter galaxies is, due to their larger photometric uncertainties, mostly defined by the detection of emission lines and not the template broadband colours themselves.
