csviscube

Computes visibility cube for a given IACT array and time period.

Synopsis

This script computes a visibility cube which is a sky cube spanned by Right Ascension, Declination and zenith angle that provides the number of hours that a given position on the sky is observable under a given zenith angle by an IACT array during a given time period.

For the moment, the script takes into account a Sun constraint, specified as a minimum zenith angle of the Sun for observations (hidden parameter sunzenith). No Moon constraint has been implemented so far.

On output, the script will provide a FITS file containing the visibility cube.

General parameters

tmin [time]
Start time of observation (UTC string, JD, MJD or MET in seconds).
tmax [time]
Stop time of observation (UTC string, JD, MJD or MET in seconds).
geolon [real]
Geographic longitude of the IACT array in degrees.
geolat [real]
Geographic latitude of the IACT array in degrees.
(sunzenith = 105.0) [real]
Minimum Sun zenith angle for observations in degrees.
(moonzenith = 90.0) [real]
Minimum Moon zenith angle for observations in degrees.
outfile [file]
Output visibility cube file.
(binsz = 1.0) [real]
Visibility cube pixel size in degrees/pixel.
(dz = 1.0) [real]
Visibility cube zenith angle bin size in degrees.
(zmax = 60.0) [real]
Maximum zenith angle of the visibility cube in degrees.

Standard parameters

(publish = no) [boolean]
Specifies whether the visibility cube should be published on VO Hub.
(chatter = 2) [integer]
Verbosity of the executable:

chatter = 0: no information will be logged

chatter = 1: only errors will be logged

chatter = 2: errors and actions will be logged

chatter = 3: report about the task execution

chatter = 4: detailed report about the task execution

(clobber = yes) [boolean]
Specifies whether an existing visibility cube file should be overwritten.
(debug = no) [boolean]
Enables debug mode. In debug mode the executable will dump any log file output to the console.
(mode = ql) [string]
Mode of automatic parameters (default is ql, i.e. "query and learn").
(logfile = csviscube.log) [filename]
Log filename.
