Fundamental parameters of 49 new star clusters in GAIA DR2

This is a database of the fundamental parameters and color-magnitude diagrams of 49 star clusters. <br> It corresponds to the study of Zhongmu Li, Yangyang Deng and Jing Chen in 2021, which was submitted to ApJS. When one use these data, please cite to that work. <br> The fundamental parameters are fitted from the color-magnitude diagrams in V and I bands, via the ASPS model and Poerful CMD code. <br> The V and I magnitudes are transformed from the Gaia DR2 magnitudes using some fitting correlations. The database contains three parts, i.e., a parameter file and three directories. They are explained as follows. The file "parameters.dat" gives the basic information, best-fit parameters from ASPS model and isochrones. <br> There are 15 columns in this file. The colums are for Name, FoF_ID, l, l_err, b, b_err, m-M, E(V-I), Z, t, f_b, f_r, Z_old, t_old, t_old_err respectively. <br> They correspond to the contents of a manuscript that was submitted to ApJS. The directory "obseved_cmds_data" contains the data of observed VI band color-magnitude diagrams of 49 star clusters. <br> The first and second columns are for V magnitude and (V-I) color, respectively. The directory "bestfit_cmds_data" contains the data of best-fit color-magnitude diagrams of 49 star clusters. <br> The first and second columns are for (V-I) color and V magnitude respectively. The directory "cmds_figs" contains the comparison figures of the observed and best-fit color-magnitude diagrams. If you have any problems with using these data, send an email to [e-mail].
