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). The size of the pad is equal to the diameter of the antenna. 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)
Read 16 pads
