CAVGSPEC

Name

cavgspec

Purpose

Robust average of a set of 1-D spectra.

Description

Calling Sequence

cavgspec,specset,bad,avgspec,avgspec_sig,badavg

Inputs

specset - a 2-D array of spectra [pixel number,spectrum number]
bad - a 2-D array of badflags [pixel number,spectrum number]

Optional Input Parameters

Keyword Input Parameters

SCALE - range of pixels to use for scaling all spectra to each other.
The default is to use all pixels for scaling.
REF - Spectrum number to use as the scaling reference. The scale
factors are determined relative to this one.

Outputs

avgspec - Final averaged spectrum.
avgspec_sig - Uncertainties of the averaged spectrum.
badavg - Bad flags for final average spectrum.

Keyword Output Parameters

SCFACTOR - Vector of relative scaling factors for each spectrum.

Procedure

Modification History

98/07/17 - Written by Chris Dalla Piazza, Lycoming College. Extracted from
the original avgspec program
98/07/17 - Added denominator filter for the sf part. Indices were also
backwards for the badflags in that section.
98/08/17, MWB, added return of bad flags on the average.
2000/10/1, MWB, added avgspec_sig return
