LDAC - Some Useful Tasks

Note

The concrete examples on this page use the LDAC catalogue D1_r_sex.cat and the shell script make_make_ssc_conf.

A tar archive with the complete set of LDAC Tools example files is here

This page contains hints on some small and useful tasks when working with the LDAC tools.

The automatic creation of a configuration file for make_ssc

When creating a merged catalogue with make_ssc after object association with associate one oftern wants to transfer all keys from an input catalogue to the merged one. The bash shell script make_make_ssc_conf can help with the tedious task of creating the configuration file for make_ssc:

user$ make_make_ssc_conf
Usage ./make_make_ssc_conf -i <cat> [-t table (OBJECTS)] [-c channel (ALL)] [-m merge (AVE_REG)]

user$ make_make_ssc_conf -i D1_r_sex.cat -t LDAC_OBJECTS -c 0
COL_NAME=X_IMAGE
COL_INPUT=X_IMAGE
COL_CHAN=0
COL_MERGE=AVE_REG
#
COL_NAME=Y_IMAGE
COL_INPUT=Y_IMAGE
COL_CHAN=0
COL_MERGE=AVE_REG
#
COL_NAME=A_IMAGE
COL_INPUT=A_IMAGE
COL_CHAN=0
COL_MERGE=AVE_REG
#

.
.

Typically the output of make_make_ssc_conf only needs to be edited slightly (if at all) before it can be used with make_ssc.
