SPLOT

Plot a polarization spectrum with a single Stokes parameter

Function

Plot a polarization spectrum with a single Stokes parameter

Description

SPLOT produces a plot of a polarization spectrum. The plot is divided into two panels. The lower panel is the total intensity, the top panel is the percentage polarization for a single Stokes parameter. If the dataset contains only one Stokes parameter that Stokes parameter is plotted. If the spectrum contains more than one Stokes parameter any one of them may be chosen for plotting. The polarization data is binned into variable size bins to give a constant polarization error per bin. Plotting is done with the NCAR/SGS/GKS graphics system.

Parameters
1 INPUT TSP, 1D

The input dataset, a spectrum which must have at least one Stokes parameter.

2 BINERR Real

The percentage error for each polarization bin.

3 DEVICE Device

The Graphics device (any valid GKS device).

4 LABEL Char

A label for the plot.

STOKESPAR Char

The Stokes parameter to be plotted (Q,U,V).

AUTO Logical

True if plot is to be autoscaled.

C IMIN Real

Minimum Intensity level to plot.

C IMAX Real

Maximum Intensity level to plot.

C PMIN Real

Minimum Polarization level to plot.

C PMAX Real

Maximum Polarization level to plot.
