• gshow now shows negative Gaussians. Previously only Gaussian values larger than zero were plotted.
• The parts of the Goddard IDL Astronomy library distributed with GBTIDL were updated just prior to this release to the most recent version available for download. This was done to fix problems involving reading large FITS files.
• The wtarray keyword in ave now works as described. Previously, ave documented the use of wtarray but that keyword was never used internally.
• The GBTIDL home page moved in late 2007 and the reference manual and user's guide documentation has been fixed to point to the new pages. Note that the downloads are still served from Sourceforge as show in these notes.

The following enhancements are included in this patch.

• Single integers can now be given to the scanrange keyword in flag. When a single integer is given it is equivalent to providing the same value in the scan parameter.
• The contributed conversion routines for NRAO 12m data can now handle the most recent data from the Kitt Peak 12m operated by ARO (the primary change in the data format is the byte ordering has change and so the need for byte swapping now has to be determined from the data).
• The contributed unipops data conversion routines (used in converting old NRAO 12m, 43m, and the recent KP12m data) now do a better job at converting more fields to their equivalent GBTIDL fields.

Introduction

These are the release notes to the first patch of GBTIDL version 2.3, known as GBTIDL version 2.3.1. See the release notes for version 2.3 for a complete list of the new features and bug fixes in version 2.3. As of ?:?? PM on ???, May ?, 2008, gbtidl at all NRAO sites corresponds to version 2.3.1 and includes the patches described in this note.

The starting point for GBTIDL documentation, bug reporting and tracking, and discussion is the GBTIDL home page.

GBTIDL is an interactive package for the reduction and analysis of spectral line data taken with the Robert C. Byrd Green Bank Telescope. The package consists of a set of straightforward yet flexible calibration, averaging, and analysis procedures (the "GUIDE layer") modeled after the UniPOPS and CLASS data reduction philosophies, a customized plotter with many built-in visualization features, and Data I/O and toolbox functionality that can be used for more advanced tasks. The entire package is written in IDL.

GBTIDL version 2.3.1 is a patch of GBTIDL version 2.3. This patched version contains a small number of bug fixes and enhancements, as described in these release notes.

Using the gbtidl command in Green Bank, Charlottesville or Socorro will automatically start this patched version of GBTIDL. If you are using a local installation, you will need to download and install this latest version from SourceForge?. This download includes the complete set of IDL scripts necessary to use GBTIDL. It is not necessary to install the previous version of GBTIDL before installing this patch.

Bug Fixes

The following bugs are fixed in this patch.

Enhancements

The following enhancements are included in this patch.

Register as a GBTIDL user

• You can do this from the User's tab on the GBTIDL web site.

Running GBTIDL in Green Bank, Socorro, or Charlottesville:

• At the unix prompt, simply type 'gbtidl'

Running your own copy of GBTIDL

IDL License

• You must have an IDL license to run GBTIDL. IDL version 6.0 and later is supported. If you don't have a license you can run GBTIDL remotely, using the computers in CV or GB. See the GBTIDL homepage for details. IDL 6.3 later is needed for large file support on a Mac.

Download and Installation of GBTIDL

• To obtain GBTIDL, download the files here
• Create a directory for the installation and unzip the tar ball:

    mkdir mygbtidl
    mv gbtidl-2.3.1.tar.gz mygbtidl/.
    cd mygbtidl
    gzip -d gbtidl-2.3.1.tar.gz
    tar -xvf gbtidl-2.3.1.tar

• go to the top level directory, 'gbtidl':

    cd gbtidl

• copy 'run_gbtidl' to 'gbtidl':

    cp run_gbtidl gbtidl

• edit the 'gbtidl' script to replace "PLACE_INSTALLATION_DIR_HERE" with the full path to the gbtidl executable script. It should then look something like this:

    export GBT_IDL_DIR=/home/mygbtidl/gbtidl

• start the package by calling the script 'gbtidl':

    ./gbtidl

• You may wish to add the installation directory to your unix path.
