IFSFIT

result = ifsf_sepfitpars(linelist, param [, perror], parinfo [, waveran=dblarr(2)])

Convert output of MPFIT, with best-fit line parameters in a single array, into a structure with separate arrays for different line parameters. Compute total line fluxes from the best-fit line parameters.

Return value

A structure with separate hashes for different line parameters. The hashes are indexed by line, and each value is an array over components. Tags: flux, fluxerr, fluxpk, fluxpkerr, nolines, wave, and sigma.

Parameters

linelist in required type=hash(lines)

List of emission line rest-frame wavelengths.

param in required type=dblarr(N)

Best-fit parameter array output by MPFIT.

perror in optional type=dblarr(N)

Errors in best fit parameters, output by MPFIT.

parinfo in required type=structure

Structure input into MPFIT. Each tag has N values, one per parameter. Used to sort param and perror arrays.

Keywords

waveran in optional type=dblarr(2)

Set to upper and lower limits to return line parameters only for lines within the given wavelength range. Lines outside this range have fluxes set to 0.
