Functions [hide private]
 
boxcar(wvl, wvl0, factor=0)
box-car filter, factor is the full width of the box filter
source code
 
gaussian(wvl, wvl0, factor=0)
a gaussian filter where factor is the gaussian width (standard deviation)
source code
 
gaussianR(wvl, wvl0, factor=1000.0)
a gaussian filter where factor is the resolving power, so that the gaussian width (standard deviation) is given by wvl0/factor
source code
 
lorentz(wvl, wvl0, factor=0)
the lorentz profile with the exception that all factors are in wavelength units rather than frequency as the lorentz profile is usually defined.
source code
 
moffat(wvl, wvl0, factor=2.5)
the moffat profile with parameters suited to Chandra Letg spectra

lorentz(wvl, wvl0, factor=0)

source code 

the lorentz profile with the exception that all factors are in wavelength units rather than frequency as the lorentz profile is usually defined. factor is the value of the so-called constant gamma
