Common AuxTel Scripts & Configurations

The following tables display the common SAL scripts used during operations with the Auxilary Telescope. These scripts are compatible with the LOVE ATQueue interface and include lower-level commands using run_command.py. The tables contain the following information:

  1. A simple description of the action/command that the script initiates to the appropriate CSCs.

  2. The script name to search for in the ScriptQueue as well as a link to its GitHub documentation.

  3. Examples of common SAL script and/or run_command.py configurations.
    Scripts that require empty configurations are labeled as “No configurations.”
