Detailed Description

PlotMSAtm: plotms class for calculating atmospheric transmission curve for bandpass plots.

Prerequisite

• CalCache module

Etymology

From "plotms", "atmospheric".

Synopsis

The PlotMSAtm class computes atmospheric transmission curves based on the algorithm in the plotbandpass task. Needed information is obtained from the bandpass table and its MeasurementSet if possible, else defaults based on observatory are used. The calculated values are returned in a vector whose size is equal to the number of channels.

Example

Motivation

This class is used by the plotms CalCache class to obtain atmospheric transmission curve values for plotting the curve overlay on a bandpass plot.
