GMOS-N Hamamatsu Users

If you have recently received GMOS-N data taken with the new Hamamatsu CCDs, the official package will not work. We have a commissioning package available that will allow for quality assessment and quicklook. Scroll down to the bottom of this page for further instructions.

Installation instructions for Ureka users

All users are encouraged to use Ureka to install IRAF and the Gemini IRAF package. Version 1.5.1 and 1.5.2 of Ureka contains Gemini IRAF package v1.13 (and a modified version of the 32-bit version of IRAF v2.16 with bug fixes specific to the Gemini IRAF package). If you are planning to use xgterm we recommend that you install 1.5.1 as there is a library conflict issue in 1.5.2. Also, while we do not expect any issues with Ureka 1.5.2 please note that we have tested the package against 1.5.1.

WARNING: The latest version of the Gemini IRAF package is v1.13.1 and it is NOT included in Ureka. This version is required for anyone reducing GMOS-S data obtained with Hamamatsu detectors. In August 2015 work on the video boards was done, and slightly changed the CCD characteristics. This new package version supports both 'flavors' of Hamamatsu. We still strongly recommend everyone else to upgrade to Gemini IRAF v1.13.1. See next section.

Installation instructions for Gemini IRAF

Ureka users (IRAF 2.16), download and install the file gemini_v1131_for_iraf_2.16.tar.gz

Users still using IRAF v2.14, download and install the file gemini_v1131_for_iraf_2.14.tar.gz. Please note that this is likely the last time we distribute an IRAF 2.14 compatible package.

These files are gzipped tar files that contain the source code and binaries for Redhat/CentOS/Fedora and Mac OS X Intel operating systems. Legacy IRAF-style installation instructions are found in the gzipped tar file itself, in the file gemini_readme.txt. However, we now recommend that you follow the installation instructions given below. (Future releases will included these revised instructions.)

  1. Download the tar.gz file you need. (We use the Ureka IRAF 2.16 in this example.)

  2. Unpack the file in a directory of your choice. In this example, we will use mypath/gemini
    1. % mkdir mypath/gemini
    2. % cd mypath/gemini
    3. % tar xvzf gemini_v1131_for_iraf_2.16.tar.gz

  3. Set your IRAF configuration to pick up the new gemini package.
    1. % cd ~/iraf
    2. There should be a file named in there. Make sure the line cl < "home$" is uncommented.
    3. In that same directory, edit or create the file Append the following lines:
      • reset gemini=mypath/gemini/
      • task gemini.pkg=gemini$
      • keep
      Make sure the trailing / (slash) is included at the end of the reset path.

  4. Now launch IRAF with pyraf or cl and the newly installed gemini package should be picked up.

Commissioning Release to Support GMOS-N Hamamatsu

Users with GMOS-N data obtained with the new Hamamatsu CCDs can use this commissioning release to do quality assessment and quick look. The CCDs are still being commissioned and have not been fully characterized. For example, things like quantum efficiency curves, essential for these CCDs, have not yet been measured. Therefore this commissioning package must NOT be used to derive scientific measurements. A complete release will be made available around July, once all the CCD characterization values are available.

If you do not have GMOS-N Hamamatsu data, use the official package above.

Download the package: gemini_v114comm.tar.gz

Installation instructions are available in the readme file. Details about the content and status of this commissioning package are available in the revision file gemini_v114comm_rev.txt
