Summary of applications

CURSA contains the following applications.

xcatview

browse and generate selections from a catalogue (easy-to-use X-windows version with a graphical user interface; see Section ),

catview

browse and generate selections from a catalogue (command line version; see Section ),

catheader

list various header information for a catalogue (see Section ),

catcopy

copy a catalogue (see Section ),

catsort

sort a catalogue (see Section ),

catselect

select a subset from a catalogue and save it as a new catalogue (see Section ),

catcoord

convert catalogue coordinates between celestial coordinate systems (see Section ),

catchart

plot a basic finding chart from a target list (see Section ),

catchartrn

customise a target list for prior to plotting it as a finding chart (see Section ),

catpair

pair two catalogues (see Section ),

catphotomfit

define photometric transformation coefficients using observations of standard stars (see Section ),

catphotomtrn

apply photometric transformation coefficients to programme objects (see Section ),

catphotomlst

list photometric transformation coefficients (see Section ),

catgrid

bin one, two or three columns from a catalogue into, respectively, a histogram, image or data cube (see Section ),

catcdsin

convert the text file version of a CDS catalogue to the CURSA STL format (see Section ),

catgscin

convert a region in the HST Guide Star Catalog to a more convenient format (see Section ),

catremote

extract a subset from a remote on-line catalogue (see Section ).

To run any of the applications you simply type its name and answer the ensuing prompts (or, in the case of xcatview dialogue boxes).

xcatview and catview provide essentially the same functionality. However, xcatview is much easier to use and is strongly recommended over catview for casual, interactive examination of a catalogue. It does, however, have to be run from a terminal (or workstation console) capable of supporting X-windows output. The only circumstances where catview is likely to be preferable are if you have a terminal which does not support X output or you are performing repetitive `batch' type operations from a script.
