Programme object catalogue

Figure  shows an example catalogue of programme objects. This example is available as file:

/star/share/cursa/photoprog.TXT

As an illustration this catalogue contains columns of both the air mass and the observed zenith distance. It does not need to contain both, but must contain one or the other. Here the zenith distance has been entered as sexagesimal degrees and minutes.

The columns do not have to have the names shown in the example. However, if you use these names you will be able to accept the defaults from the prompts in the CURSA applications.

The catalogue can contain additional columns; indeed a programme catalogue will often contain celestial coordinates and/or object names. Also, if you are calibrating multi-colour photometry you could prepare a single catalogue containing the instrumental magnitudes in all the colours observed. Obviously the columns for magnitudes in different colours would have to have different names. If you did not observe all the objects in all the colours simply use the STL mechanism for indicating null values (see Section ) to represent the missing measurements.
