Inspecting SMA Data

corrPlotter:

This program can be used to plot the amplitude and phase of the correlator pseudo continuum, as a function of time. Options allow the display of a single sideband, selected baselines, phase closure, etc. The program can be controlled by keyboard commands or via a menu interface.

On the R&G linux computers, type, for example:

/2006/corrPlotter -m -f /2006/science/mir_data/070903_04:04:31

To resize the plot window, click and drag a corner. Keyboard commands are typed directly on to the plot window. To undo a command, type the previous command again, or click a second time on the source name, etc. A table of common keyboard commands follows:

Keyboard command	What is displayed
h	List of "Keyboard shortcuts". Type any key to get display back.
u	USB only. Type "u" again to get both sidebands back
l	LSB only
1-9	baselines that include the typed number
0	all baselines
c	closure phases
left click on source name	only that source
right click on source name	All sources except clicked source, e.g., if want to rescale amplitudes.
q	quit

whatishere:

This program can be used to obtain a summary of the contents of your science data directory. It obtains information from the plot_me files.

On the R&G linux computers, type, for example:

/2006/whatishere /2006/science/mir_data/080321_18:58:58
