The pre-observing test should be carried out using the Monitor and Control system and is aimed at making sure that all the commands in the glish script are valid. This provides another round of debugging the glish script. The author of the glish script should sign-up for GBT test time at the GBT Equipment Reservations web page. The scripts should be tested only during the requested test time. No scans or observations should be done during these tests. The goal of this test is to make sure that the device gets setup correctly from many and various initial conditions for the device. This will also test the glish script for completeness, i.e. will the script cause the device to be setup the same way every time for the desired observation.
