## Key points

- Construction of a comprehensive photometric catalog in the UDS field using deep multi-wavelength imaging
- Catalog covers 0.9 sq. deg. area with data from 24 filters (MegaCam-uS to Spitzer-IRAC bands)
- Includes approximately 188,564 galaxies with stellar masses >10$^{8}$ solar masses and K-band total magnitudes below K < 25.2 AB at redshifts between 0.2 and 8.0
- Provides essential data for extragalactic studies such as photometric redshifts, redshift probability distributions, rest-frame absolute magnitudes, and colors derived through template-fitting using eazy-py code
- Photometric redshift errors are minimal (<3-4%) for redshifts lower than 4 across varying brightness levels in the K-band and stellar mass range of 10$^{8}$-10$^{12}$ solar masses
- Derives crucial stellar population properties like stellar mass, star-formation rate, and dust extinction by modeling SEDs using FAST and Dense Basis codes
- Publicly available photometric catalog enables scientific investigations spanning redshifts from 0.2 to 8.0 – covering about 95% of cosmic history
- Offers insights into galaxy evolution over cosmic time scales by combining deep NIR imaging across a wide area

## Summary

We present the construction of a comprehensive photometric catalog in the UDS field using deep multi-wavelength imaging. The catalog covers an expansive area of 0.9 sq. deg. and includes data from 24 filters ranging from MegaCam-uS to Spitzer-IRAC bands. It contains approximately 188,564 galaxies with stellar masses exceeding 10$^{8}$ solar masses and K-band total magnitudes below K < 25.2 AB at redshifts between 0.2 and 8.0. The catalog provides essential data for extragalactic studies such as photometric redshifts, corresponding redshift probability distributions, and rest-frame absolute magnitudes and colors derived through template-fitting using the eazy-py code. Photometric redshift errors are minimal (<3-4%) for redshifts lower than 4 across varying brightness levels in the K-band and stellar mass range of 10$^{8}$-10$^{12}$ solar masses. Additionally, we derive crucial stellar population properties like stellar mass, star-formation rate, and dust extinction by modeling spectral energy distributions (SEDs) using FAST and Dense Basis codes. The publicly available photometric catalog alongside associated catalogs of photometric redshifts and stellar population properties enables scientific investigations spanning a broad spectrum of redshifts from 0.2 to 8.0 – effectively encapsulating about 95% of cosmic history. This study offers valuable insights into galaxy evolution over cosmic time scales by combining deep near-infrared (NIR) imaging across a wide area. The high-quality data presented here provides researchers with a unique opportunity to explore various aspects of galaxy formation and evolution throughout different epochs in our universe's history.
