spcreadr

Purpose

Reads a Galactic SPC file.

Synopsis

 

x = spcreadr(filename,subs,wlrange,options)

[data,xaxis,auditlog] = spcreadr(filename,subs,wlrange,options)

Description

SPCREADR reads a Galactic SPC file.

INPUT:

           filename =   text string with the name of the SPC file.

OPTIONAL INPUTS:

                   subs =   [], scalar or vector indicating the sub-files to read, e.g. [3] reads sub-file 3, [3:9] reads sub-files 3 to 9, {default reads all sub-files} and

             wlrange =   [], two element vector (inclusive endpoints) of the wavelength range to return {default returns the entire wavelength range}.

OUTPUTS:

                         x =   a dataset object containing the spectrum, or

                   data =   a data array with measured intensities,

        xaxis =   vector containing the wavelength axis, and

     auditlog =   char array with the log from the file.

Options

             options =   a structure array with the following fields:

              display:   [ 'none' | 'intersect' |{'interpolate'} ], defines action taken when the x-axes of two spectra being read do not match. The options are:

                                 'intersect' returns only the points where the spectral x-axis values overlap excatly.

                                 'interpolate' returns the overlapping portions with linear interpolation to match spectral points exactly. As no extrapolation will be done, the returned spectra will cover the smallest common spectral range.

                                 'none' ignores x-axis differences as long as the number of data points is the same in all spectra.

    textauditlog:   [ {'no'} | 'yes' ], governs output of audit log contents. When 'yes', the auditlog is returned as a raw text array. Otherwise, the auditlog is returned as a structure with field names taken from  auditlog keys.
