in IDL enter:
uv_coverage, /baseline_labels, /baselines2plot, /meters, /over, source='SOURCE', /ps, /range, /one, /UTs
Example:
uv_coverage, source='NGC1365', /UTs, /over, /meters, range=150
Where
/meters: if set, plot axes in meters
/over = /overplothapoints: overplot HA points
SOURCE must be replaced by a source's name (e.g. NGC 1365) as it appears in sources.txt
/ps: outputs PS file in $WorkingDir/POSTSCRIPTS/uv_coverage_$SOURCE.eps
/range: specify range of the plot
/one = /onequadrant: plot only top right quadrant
/UTs: plots points only for UTs
Specify the baselines and Hour Angles (HA) at which you want to observe your source in hapoints.txt. Remember: HA = LST - RA where LST is the Local Sidereal Time and RA the Right Ascension.
If you add a * in front of the hour angle that you specify in hapoints.txt the respective HA-point will be displayed as a filled diamond, as opposed to open diamonds for other points. This is useful if you want to point out e.g. which uv-points you have already observed, and which you propose to observe, e.g. to make the HA=-2 point on the UT3-UT4 track a filled diamond, write:
baselines U1U2 U2U3 U1U3 U2U4 U3U4 U1U4 NGC1365 ; -999 -999 -999 -999 *-2 -999
Before compiling and running uv_coverage.pro you must change to the directory 'VERSION_1.1' (or appropriate) within the package directory.
Files in package:
uv_coverage.pro
