A simple gaussian line profile. If the width is , then it is treated as a delta function.
where :
par1 = line energy in keV par2 = line width (sigma) in keV par3 = redshift K = total photons/cm/s in the line
par2 = line width (sigma) in keV
par3 = redshift
K = total photons/cm/s in the line
, then it
is treated as a delta function.
