OSIDVFIT

Name

osidvfit

Purpose

Find the linear fit coefficients for a spectrum for each order

Description

The spectrum and a reference to be divided by are input. The spectrum is
divided by the reference and this divided spectrum is then filtered for noise
and deviant points. A linear fit is then applied to each order of the
filtered divided spectrum.

Calling Sequence

osidvfit,calib,divspec

Inputs

calib - The calibration information for the spectrum
spectrum - The spectrum to be fit
avgspec - The spectrum to be used as a divisor

Optional Input Parameters

Keyword Input Parameters

BAD - The bad flags associated with the average spectrum

Outputs

fit - The linear fit coefficients for each order; this is in the form of a
2-d array with the fit[0,i]=yint and fit[1,i]=slope where i is the
order of the spectrum
