Verify filter wheel operation

 In order to test the filter wheel, as well as to verify the software configuration, you should first initialize the filter wheel:

This command will move the filter wheel to its home position. If you receive any error from this operation, notify the Palomar crew immediately to have the problem rectified. If you have time, you should return to the dome to verify that the filter wheel is indeed in its home position.

In order to use a filter in the filter wheel, you will also need to set up the filter name table. This procedure is quite different between the two telescopes; relevant commands include:

Be sure to assign a name to the slot containing the calibration filter, as well as to an empty slot in the wheel, for testing purposes. After inserting observation filters, you will want to assign names to their slots as well. Note that the initial letter of each filter name is significant; no two filter names should begin with the same letter. Filter names on the 200-inch telescope should be given in capital letters.
