This page contains instructions for downloading and installing the LMS software used for LUCI mask generation, as well as some of the release notes for this latest update.

System Requirements

The MMS 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 can be found here:

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 here: 

OS-X (Mac) users:

  1. Skycat and LMS require X-windows to be installed on your system.  A pre-compiled binary for X-windows can be found here from Xquartz  The latest version is 2.7.11 and works on all versions of OS-X.
  2. 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:

Installing MMS

The Tarballs are below:

 NEW!!  MMS_V2.0.tgz


  • 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]/MMS_V2.0.tgz

    This 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 in mms_v2.0.0/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 mms_v2.0 is placed in your home directory and skycat is in your path,
    $MMSROOT to match the path for your MMS directory, and the “call skycat” path located in mms_v2.0/bin/

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
