These are the data sets used for the article:"Deep Spectroscopy with DESI for Photometric Redshift Training and Calibration" by Dey et al. Following is a brief description of the files. merged_cat_LSST_WL_Y1.fits : This file contains crossmatched HSC photometry, DESI redshift pipeline outputs and visual inspection labels for all the objects described in the article. HSC_COSMOS_I_mag_lim_24.8.fits : Parent catalog of all objects in the DESI-COSMOS field which was used to select targets from. HSC_XMM_I_mag_lim_24.8.fits : Parent catalog of all objects in the DESI-XMMLSS field which was used to select targets from. COSMOS_LSSTY1_target_list.fits : Catalog of objects in the DESI-COSMOS field selected from the parent catalog after quality and magnitude cuts and downsampling. The DESI fiber assignment algorithm was run on this catalog. XMM_LSSTY1_target_list.fits : Catalog of objects in the DESI-COSMOS field selected from the parent catalog after quality and magnitude cuts and downsampling. The DESI fiber assignment algorithm was run on this catalog. FIGURE-XX.zip: Data points plotted in Figure-XX in the paper.
