MANGA里面用了11个库,下面的主要是对DAP里面的用的库的注释

M11-STELIB

  • stellar library STELIB by Le Borgne et al. (2003).
  • Usable wavelength range for all ages is 3201.0 - 7900.0 AA!
  • 原始分辨率:0.5 A/pixel, and a FWHM of the resolution element of 3.1 angstroms. Resampled this to 1 A/pixel to reduce the oversampling of the spectra. The resampled spectra are named *_s.fits; the original spectra do not have the _s suffix. When constructing the library to fit the spectra, only the *_s.fits spectra are read.
  • IMF
'.ss' ==> Salpeter IMF
'.kr' ==> Kroupa IMF
'.cha' ==> Chabrier IMF
  • DAP 只用了3个金属丰度,一共85个SSP,
