ИСТИНА

Among 660 galaxies surveyed by the IFU project CALIFA there are about 100 early-type disk galaxies - of S0 or S0/a type. I present arcminute-sized maps of the Lick indices H-beta, Mgb, Fe5270, and Fe5335 for this subsample. The SSP-equivalent stellar ages and magnesium-to-iron ratios in the large-scale disks of the nearby lenticular galaxies are analyzed, and the history of disk galaxy evolution is specified relating to the environment properties.
