peakwave_asymgauss

pyetc.etc.peakwave_asymgauss(lpeak, sigma, skew, dl=0.01)

compute the asymetric gaussian wavelength paramater to get the given peak wavelength

Parameters:

lpeakfloat

peak wavelength in A

sigmafloat

sigma in A

skewfloat

skew parameter (0 for a gaussian)

dlfloat

step in wavelength (A, Default value = 0.01)

Returns:

float

wavelength (A) of the asymetric gaussian
