Type:: str

abun#

Type:: dict

Av_extinction#

Av used for observation isochrones (Cardelli et al. (1989) + O’Donnell (1994) with RV=3.1.)

Type:: float

ages#

List ofi available ages.

Type:: list

num_ages#

Number of ages.

Type:: int

hdr_list#

List of table column names.

Type:: list

isocmds#

Type:: Numpy array

Examples

>>> isocmd = readisocmd.PADOVA('PARSEC_1.2S_feh_p0.00_GGBPGRP.iso.cmd')
>>> age_ind = isocmd.age_index(7.0)
>>> G = isocmd.isocmds[age_ind]['G']
>>> G_BP = isocmd.isocmds[age_ind]['G_BP']
>>> G_RP = isocmd.isocmds[age_ind]['G_RP']
>>> plt.plot(G_BP-G_RP, G) #plot the CMD for logage = 7.0
