LMS Install
System Requirements
The LMS software requires a working installation of ESO’s Skycat software. That software is still maintained for Linux and OS-X (Mac) operating systems (the current version is 3.1.4). Information regarding installation of pre-compiled binaries for Skycat is available.
Installing Skycat may require you to specially configure the repositories used to obtain the binaries. That information is provided (by ESO) for various Linux flavors and OSX at http://www.eso.org/sci/observing/phase2/ESO_sw_repos.html
OS-X (Mac) users:
- Skycat and LMS require X-windows to be installed on your system. A pre-compiled binary for X-windows can be found at XQuartz. The latest version is 2.8.5.
- The preferred method of installing Skycat is using Macports. ESO provides a guideline to installation. The Macports website provides more information.
Users may also compile the Skycat source code on their own, rather than install pre-configured binaries. That information is found at the bottom of the webpage: http://www.eso.org/sci/observing/tools/skycat/skycatDownload.html.
Installing LMS
For Version 3.1.2: Distribution files for both OSX (Mac) and linux are available here:
NOTE: Updated version release 08/04/2019 that addresses accuracy issue for slit positions. This issue resulted in a slight distortion that could impact positions of outer edge of the 4′ FOV in v3.1.1 or prior up to 0.1″.
- Mac OS X
Drop the untarred file into your /Applications folder and you are ready to Get Started.cd /Applications
tar -zxvf [tar file location]/LMS_v3.1.2_mac.tgzThis distribution assumes that Skycat has been installed via Macports. If Skycat was installed by other means, or is not located in the standard /opt/local/bin/skycat directory, then edit the “call skycat” directory located near the end of lms.sh in LMS_v3.0/bin to point to your Skycat directory.
- Linux (Fedora, Scientific Linux, and CentOS, likely to be compatible with other distributions).
Untar the file. If the LMS_v3.1 is placed in your home directory and skycat is in your path,
$LMSROOT to match the path for your LMS directory, and the “call skycat” path located in LMS_v3.0/bin/lms.sh.
The application is distributed via Google Drive, you should use your web browser to download the files, follow the Google Drive instructions to download the file
For Version 1.65: A tarball of LMS_v1.65 and the manual, which outlines detailed use of the LUCI Mask Software, is available.
