This repository provides all data that can be used to reproduce figures in following paper: Luminosity and stellar mass functions of faint photometric satellites around spectroscopic central galaxies from DESI Year-1 Bright Galaxy Survey ----------------------------------------------------------------------------------Description of contents: #tab1.txt.tar.gz: Data for Figure 1 of the paper. After decompressing the tar file, there are two separate files named 'tab1.txt' and 'tab1_mean_median_scatter.txt'. tab1.txt contains data for black scatter points in Figure 1, and tab1_mean_median_scatter.txt contains data for the mean, median and scatter. #tab2.txt.tar.gz: Data for Figure 2 of the paper. After decompressing the tar file, there are three separate files named 'tab2_black.txt', 'tab2_green.txt' and 'tab2_red.txt', corresponding to the black plain, green plain and red hatched histograms in Figure 2. #tab3.txt: Data for Figure 3 of the paper. #tab4.txt.tar.gz: Data for Figure 4 of the paper. After decompressing the tar file, there are four separate files named 'tab4_desi.txt', 'tab4_sdss.txt', 'tab4_matched_desimass.txt' and 'tab4_matched_sdssmass.txt', corresponding to the measurements in Figure 4 based on DESI stellar mass, on SDSS stellar mass, on the matched part between DESI and SDSS but using DESI stellar mass, and on the matched part using SDSS stellar mass, respectively. All 10 panels with stellar mass above logM_\ast/msun>7.1 are merged in a single file for the most massive panel to less massive panels, with different panels separated by an empty line. #tab5.txt.tar.gz: Data for Figure 5 of the paper. After decompressing the tar file, there are two separate files named 'tab5_cigale.txt' and 'tab5_fastspecfit.txt', corresponding to the measurements based on Cigale and DESI stellar masses, respectively. All 10 panels with stellar mass above logM_\ast/msun>7.1 are merged in a single file for the most massive panel to less massive panels, with different panels separated by an empty line. #tab6.txt.tar.gz: Data for Figure 6 of the paper. After decompressing the tar file, there are two separate files named 'tab6.txt' and 'tab6_median_scatter.txt'. tab6.txt contains data for scatter points in Figure 6, with the third column indicating FLAGINFRARED, which is adopted to color code the points in gray scale. tab6_median_scatter.txt contains data for the associated median and scatter. #tab7.txt: Data for Figure 7 of the paper. All 10 panels with stellar mass above logM_\ast/msun>7.1 are merged in a single file for the most massive panel to less massive panels, with different panels separated by an empty line. #tab8.txt: Data for Figure 9 of the paper. All 10 panels with stellar mass above logM_\ast/msun>7.1 are merged in a single file for the most massive panel to less massive panels, with different panels separated by an empty line. -----------------------------------------------------------------------------------System requirements: All data files are in ASCII formates, without particular system requirements to read. -----------------------------------------------------------------------------------Additional comments: Data associated with Figures 8 and 10 are provided in tables of the main text, and are thus not separatedly provided.
