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 [real]

Start time of the observation.

tmax [real]

Stop time of the observation.

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

(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.
