| Description | Hyperspectral cube line fitting for velocity maps
▾
It takes a CALIFA hyper spectral data cube as input, a catalog of redshifts for galaxies in the Califa data collection and a list of emission lines to detect. It produces a set of 4 maps with the H-alpha amplitude, the radial velocity extracted from the line shift and the velocity dispersion in the field of the galaxy image, plus the residual error maps.
