AHELP for CIAO 4.2


Context: sl.crates_contrib


Utility routines for Crates (CIAO contributed package)


require ("crates_utils");


The crates_utils module provides utility routines for CIAO users, and is provided as part of the CIAO contributed scripts package.

Loading the routines

The module can be loaded into ChIPS, Sherpa, or S-Lang scripts by saying one of the following:

require ("crates_utils");
require ("crates_contrib");

where the second line will load in all the Crates contributed routines, not just the utils module.


The utils module currenly provides two routines:

  • write_columns() - write out a set of arrays to a file as a table (ASCII or FITS format)
  • make_table_crate() - create a table crate from a set of arrays

See the ahelp file for the routine and the contributed scripts page for further information.


See the bugs pages for an up-to-date listing of known bugs.
