Dataset for "BayeSED-GALAXIES II. Bayesian full spectrum analysis of galaxies and application in the CSST wide-field slitless spectroscopy survey"

This is the supporting dataset for the BayeSED-GALAXIES II paper, including reshift, morphological and stellar population parameters, simulated CSST photometry and slitless spectra for ~100,000 galaxies ramdomly selected from the DESI DR9 seed galaxy catalogue as described in Gu et al. (2024).DESI9_phot_BayeSED3.tar.bz2: output file of BayeSED3 in hdf5 format from the Bayesian analysis of 5 bands DESI DR9 photometryCSST_grism_CESS.tar.bz2: output file of CESS in hdf5 format, see Wen et al. (2024) for the detailed method of simulationmock_csst_data.tar.bz2: csst mock catalog in txt format, obtained from the merge of partial information in the above two files, suitable as input file for BayeSED3 to test the performace of the future CSST slitless spectroscopic observations.
