Description

This tool allows the user to create so called skycatalog tables readable by the Viewer tool. This can be done from ASCII tables or componentlists. It also provides a front-end to the table tool to manipulate the structure of the skycatalog.

Example
Here is a small example on how to convert an ascii table ``my.ascii'' to an AIPS++ table ``my.tbl'':

The ASCII file looks like this:

Name	No	RA	DEC	NED-ID	Max	mom0
A	A	A	A	A	R	R
NED	16	19:44:47	-14:46:51	NGC6822ee	24.255	159.8
NED	22	01:04:46	+02:07:04	IC1613e	13.002	328.1

include 'skycatalog.g';
sca := skycatalog('myscat1.tbl');
sca.fromascii(asciifile='my.ascii',hasheader=T,longcol='RA',latcol='DEC');
# cosmetics
sca.mergecolumns("Name No");
sca.done()

Example
An example using a componentlist:

im := imagemaketestimage()
cl := im.findsources()
sca := skycatalog('myscat2.tbl')
sca.fromcomponentlist(cl)
sca.done()
# That's it !
