IPCS2STOKES

Reduce IPCS spectropolarimetry data.

Function

Reduce IPCS spectropolarimetry data.

Description

IPCS2STOKES reduces data obtained with the AAO Pockels cell spectropolarimeter with the IPCS as detector. The data is read in the form of Figaro files each containing a pair of A and B state frames forming a single observation. Within each A and B frame there are four spectra corresponding to the O and E rays for each of two apertures (A and B). These spectra are combined to derive a Stokes parameter spectrum in TSP format.

Parameters
1 FIGARO Char

The input Figaro data file.

ASTART Integer

The Start column for the A aperture data.

BSTART Integer

The Start column for the B aperture data.

OESEP Integer

The distance in columns from the start of the O spectrum to the start of the E spectrum.

WIDTH Integer

The number of columns to include in each extracted spectrum.

APERTURE Char

The aperture containing the star (A or B).

STOKESPAR Char

The Stokes parameter (Q,U,V).

OUTPUT TSP, 1D

The Output dataset.
