Below is a list of tasks, most of which will be converted into engineering
tasks in the CARA Remedy database. Note that there are different types
of tasks: some can be done in the daytime, some are lower priority, etc.
These are coded as follows:
- An asterisk (*) indicates a lower priority task.
-
A (D) means that this is a daytime or closed dome test.

-
Determine ROTZERO,
-
Determine the guider pointing origin (REF).
-
