top ifsf_manygauss

IFSFIT

result = ifsf_manygauss(wave, param)

This function is input to MPFIT, which uses it to compute the emission line spectrum of multiple Gaussian emission lines simultaneously. This routine assumes constant dispersion (in A/pix), and uses this fact to optimize the computation by working with smaller sub-arrays. Use MANYGAUSS_SLOW (which works with large arrays) for data without constant dispersion.

Return value

An N-element array containing an emission-line spectrum.

Parameters

wave in required type=dblarr(N)

Wavelengths

param in required type=dblarr

Best-fit parameter array output by MPFIT.
