CALACS

Format: %calacs.e -tv ipppssoot_raw

Either the name of the raw dataset for a single exposure, or the name of an association's FITS file. Use the name without the extension. See the examples below.

This depends on the calibration switches which have been set.

The input datasets must reside in the user's working directory. If the user wishes to use his own calibration tables, user must edit the appropriate keywords in the headers.

In order to run 'calacs' from the command line, you need to account for two primary things: the definitions of the directories where the reference tables and images are located (jref and jtab), and the command line options.

Under Unix, you can set the 'jref' and 'jtab' variables using 'setenv' in a manner such as:

	setenv jref /some/directory/ref
	setenv jtab /some/directory/tab

As for the command line options, you have the following currently available switches:

	-t -v -s
where 
	-t	prints time stamps during processing
	-v	prints more verbose messages during processing
	-s	save intermediate files created during processing
	-q	quiet mode: only send messages to trailer files, not STDOUT

There is also a '-d' switch for outputting additional debugging messages during some processing steps, but you should not need this option for your tests.

The syntax for running 'calacs' has been simplified as much as possible:

	calacs.e [-tvsqd] input

where input will be the rootname and suffix of either an input ASN table or single exposure or even rootname of sub-product listed in an ASN table.

Therefore, to process an entire ASN table named 'jxaa01010_asn.fits', you would use:

	calacs.e -tv jxaa01010_asn
or	calacs.e -tv jxaa01010		-although this is NOT recommended!

To process a single exposure, either part of an ASN table or not, named 'jxaa0100a_raw.fits', you would use:

	calacs.e -tv jxaa0100a_raw	- suffix required here
					  (in this case '_raw')

To process a sub-product 'jxaa01011' specified in the ASN table 'jxaa01010_asn.fits', you would use:

	calacs.e -tv jxaa01011		- no suffix to append here

> You do not append the suffix to this input name, since you don't know what it is. This is the only case where the suffix would not be appended to the rootname as input to 'calacs'.
