查看“Stellar library”的源代码

[[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
''' 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
：85个读入的顺序是按照文件名排序的，可以在~/MANGA/DAP/1.1.1/external/templates/m11_stelib目录下，用ls *_s.fits查看

*MILES extended
:covers the optical and the infrared wavelength range between 3500 and 50000 
: based on empirical stellar spectra
:Age> 1 Gyr, for metallicities between [Fe/H] = -0.40 and 0.26, for initial mass functions of various types and slopes, and on the basis of two different sets of isochrones.
