The spectroscopic data are in the "spec_data" folder, and photometric data are in "phot_data.csv" file.


PHOTOMETRIC DATA:

ID: Name of star clusters.
RA_deg, Dec_deg: The right ascension and declination of star clusters, given in degrees.
E(B-V)_comb: E(B-V) value collected in different works. (described in the main paper)
GXfuv, GXnuv: The FUV and NUV filters of the GALEX survey.
SGu, SGv: The u_sages and v_sages filters of the SAGES survey.
PSg, PSr, PSi, PSz, PSy: The g, r, i, z, y filters of the Pan-STARRS survey.
2Mj, 2Mh, 2Mk: The J, H, Ks filters of the 2MASS survey.


SPECTROSCOPIC DATA:

Each FITS file contains the spectrum of a star cluster, including wavelength, normalized flux, and associated flux uncertainties. The spectrum is first flux-calibrated and then normalized by dividing by the 95th percentile of its full flux distribution.
