Catalog_Plot Module¶
This is the Catalog_Plot module. It is a library of wrappers around plotting functions in the plot_lib module, whose functions are named according to the classes whose data they help plot.
A library of wrappers which call plotting functions in the SSINS.plot_lib library. Each function is named according to the class that they plot.

Plots an incoherent noise specturm and its mean-subtracted spectrum
- Parameters
INS (INS) – The INS whose data is to be plotted. Required
prefix (str) – A prefix for the output filepath e.g. “/outdir/plots/obsid” Required
file_ext (str) – The type of image file to output
xticks (sequence) – The frequency channel indices to tick in INS waterfall plots.
yticks (sequence) – The time indices to tick in INS waterfall plots.
vmin (float) – The minimum of the colormap for the INS (non-mean-subtracted)
vmax (float) – The maximum of the colormap for the INS (non-mean-subtracted)
ms_vmin (float) – The minimum of the colormap for the mean-subtracted INS
ms_vmax (float) – The maximum of the colormap for the mean-subtracted INS
data_cmap (str) – The colormap for the non-mean-subtracted data
xticklabels (sequence of str) – The labels for the frequency ticks
yticklabels (sequence of str) – The labels for the time ticks
aspect (float or 'auto' or 'equal') – Set the aspect ratio of the waterfall plots.
title (str) – The title to use for the plot.
title_x (float) – x-coordinate of title center (in figure coordinates)
title_y (float) – y-coordinate of title center (in figure coordinates)
use_extent (bool) – Whether to use the INS metadata to make ticks on plots. Easier than manual adjustment and sufficient for most cases. Will put time in UTC and frequency in MHz.
backend (str) – Which matplotlib backend to use.
extent_time_format (str) – If ‘jd’, will use the time_array of the object. is ‘lst’, will use the lst_array of the object.
convert_times (bool) – Whether to convert times in extent. Will convert jd into UTC and lst into hourangles.

Plots a histogram of the amplitudes of the visibility differences that result from sky subtraction.
- Parameters
