IMFs for the SSPs library


The Single Stellar Population (SSP) SEDs library files have names in the form

Z<metallicity>.<imf>

For instance Z02.sal is a library with solar metallicity and Salpeter imf. The Initial Mass Functions adopted to compute the libraries included in the distribution are Salpeter, Scalo, Miller and Scalo, and Kennicut 92,. Corresponding file extensions are sal, sca, msc, and sken. Details on the IMF parameters are given in the table below.
