Plotconfig

Return to Analysis Utilities

This page documents the plotconfig function of Python module analysisUtils.

This function will make a plot of pad locations for any standard telescope configuration known to CASA (not limited to a specific observed ms). It also returns an array of the baseline lengths, sorted from shortest to longest. See also obslist.

Usage

au.plotconfig(telescope="", config="", figfile="", list=False, limits=None, gridlines=True, listconfig=False, cofa=[], title="")

telescope: name of the telescope (see below), or 'file'

config: name of the configuration for the specified telescope, or any user-supplied .cfg file if telescope='file'

figfile: a specific filename to give to the png (or True for automatic name generation)

gridlines: optional Boolean parameter to show dotted grid lines on major tick marks

limits: optional parameter for plot range: [x0,x1,y0,y1]

list: optional Boolean parameter to print the list of baseline lengths

listconfig: optional Boolean parameter to print the .cfg file

cofa: center-of-array coordinates [x,y,z]; if [], then use the value in CASA

title: title for plot (default is "telescope config")

Examples

Example 1. List the available telescopes and configurations.

# In CASA
au.plotconfig()

Telescope and configuration available to plot:
aca: i, ns, tp
alma: cycle0.compact, cycle0.extended, cycle1_1..6, 1..28
carma: a, b, c, d, e
meerkat
pdbi: a, b, c, d
sma: subcompact, compact, compact.n, extended, vextended
vla: a, bna, b, cnb, c, dnc, d
WSRT

Example 2. Plot the antenna pad locations for the ALMA Cycle 0 compact configuration.

# In CASA
CASA <3>: au.plotconfig('alma','cycle0.compact',figfile=True)
