Stellar library

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.
