TOPZ for New Christians

Product Information

Below we give an overview of the impact that different inputs and configurations have on the TOPz performance for the r< 22 mag sub-sample of galaxies (1989 sources) when comparing the photometric redshift estimations to the spectroscopic redshifts.

Besides improving photos that were already sharp, it can fix photos with slow shutter speed or where it’s slightly out of focus! In total, the resultant test catalogue consists of 4457 galaxies while a brighter ( r< 22 mag) sub-sample with 1989 objects is used in most of the tests.Põltsamaalt on jõudnud turule uue põlvkonna valmissupid ja -toidud: tippkokkade retsepte ja kohalikku toorainet kasutades valminud eestlaste lemmikmaitsed, mis on kvaliteetsed ja ilma lisaaineteta. The corresponding weighted averages are given with the dashed vertical, slightly darker, lines (z_w1d and z_w2d).

When we increase the training size, the mean values for these characteristics remain almost the same while the variance grows. On the other hand, the usage of narrow-band photometry requires the templates to be realistic and representative also in details like spectral line strengths and ratios.Limiting the number of spectra in the template set improves the redshift accuracy up to 5%, especially for fainter, noise-dominated sources.
