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
ssp_M11_MILES.ss.z001 （z=0.01）
- 24 ages, 200 Myr to 15 Gyr,3201.0 - 9296.5 AA 12192 flux point
ssp_M11_MILES.ss.z002 （solar metallicity）
- 39 ages, 30 Myr to 15 Gyr
ssp_M11_MILES.ss.z004 （z=0.04）
- 22 ages, 400 Myr to 15 Gyr
