Align Chandra Event Files

IMPORTANT NOTE: The information and script in this page are obsolete and have been replaced by the CIAO thread Merging Data from Multiple Imaging Observations. This page will be removed in June 2005.

Summary

Align_evt is a Perl script which generates dmhedit commands to align Chandra event files for multiple observations of the same field, based on detected sources. This is a user-contributed script and is not supported by the CXC Helpdesk. The author (Tom Aldcroft) will attempt to answer any user questions.

A more detailed description of the program and its usage is available here or by running the program with the -help flag:

UNIX> align_evt -help

Download and Installation

Align_evt is available for download here.

It has been tested under Solaris, running CIAO 2.x and Perl 5.6.0. Your mileage may vary. The script uses the Perl modules Getopt::Long and POSIX, which can be downloaded from CPAN.

To run the program, you will need to make it executable

 
chmod +x align_evt

and probably need to change the first line of code to point to your local perl executable, for instance:

#!/usr/bin/perl -w
