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. CATEGORY: Spectroscopy 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 KEYWORD OUTPUT PARAMETERS: COMMON BLOCKS: SIDE EFFECTS: RESTRICTIONS: PROCEDURE: MODIFICATION HISTORY: 98/06/24 - Written by Chris Dalla Piazza, Lycoming College
