getLoadTemperatures

Gets the calibration device load temperatures (in Kelvin) from the ASDM_CALDEVICE table (if present). Returns a dictionary keyed by antenna, then scan number. Keys are provide for both the antenna name and ID. If the table is not present, it returns a dictionary with the default temperatures for these loads.

Usage:

au.getLoadTemperatures(vis, antenna=None, doplot=False, warnIfNoLoadTemperatures=True)
  • if doplot=True, plots the temperature timestamps compared to the scan timestamps
  • antenna: only used if doplot==True

Examples:

A 2-antenna dataset, with the table present:
CASA <31>: au.getLoadTemperatures('uid___A002_X6b15c4_X21.ms')
