Catalogues

The TCS contains a catalogue of objects. This catalogue may be viewed by typing:

USER>out term

The form of the output for each object is as follows:

Name RA(hrs) RA(mins) RA(secs) Dec(degs) Dec(') Dec('') Equinox

E.g: ngc1068 02 42 40.2 -00 00 48 J2000

To add objects to the catalogue, on the TCS type:

USER>source name RA RA RA Dec Dec Dec Equinox
USER>add

Note that the "Equinox" parameter should be specified by a letter immediately followed by a 4 digit year.

You may also add a list of objects to the catalogue all at once. To do this requires a text file with all the objects listed one per line in the following format:

name RA RA RA Dec Dec Dec Equinox

This file must have a ".cat" extension to it and you must copy it to the directory /jkt/cat on lpss10. To include these objects in the catalogue, on the TCS type:

USER>inc jkt:[cat]filename.cat
Note that "filename" refers to the name of your catalogue file.

There are a couple of other commands useful for editing the catalogue. These are:

USER>remove name
This deletes a catalogue entry called "name".

USER>erase
This clears the catalogue of all entries.

USER>mark name
This stores the current telescope position as an object called "name". It will only work if the telescope is currently tracking.

Note that all of the above commands may be issued from the TCS regardless of whether the telescope is in computer mode or not.
