AXAF FLIGHT ACIS COMMAND SEQUENCES

We have decided that ACIS activities shall be created in a tab-separated ASCII format so that the various users will be able to read the data into their SW of choice with ease. The following file contains a description of the columns which are now contained in the activity descriptions.

A "cheat-sheet" for filling in ACIS Timed Exposure paramater blocks. The latest status of development of these procedures by SOT and FOT according to Paul (not the FOT which may be more up to date). The color coding in the list of procedures below means:

The links below point to the Tab-Separated Values (TSV) ASCII files, the Postscript files, and the ASCII LaTeX files. The page is under construction and will be updated frequently. The TSV files only have the command sequences and do NOT have the prose which accompanies each procedure (which is contained in the Postscript and LaTeX files).

1.0 ORBITAL ACTIVATION PROCEDURES

3.0 ACIS STORED COMMAND SEQUENCES

These originated from Royce and were provided in HTML format from Dan Muleady. These are the draft command procedures which will be burned into the spacecraft sometime soon. There are three SCSs for ACIS, one for load shedding in a power emergency, one for eclipse exit powerup, and one for radiation alert response. The first version had the byte-swapping problem in the ACIS SW command packets. The command loads were re-generated and put on the spacecraft again in October, 1998.

4.0 ACIS ``ATOMIC'' PROCEDURES

5.0 ACIS CONTINGENCY PROCEDURES

6.0 ACIS Real Time Sequences (RTSs)

7.0 FOT Procedures to Respond to an Unsafe ACIS

8.0 FOT ER Request form for specifying unusual tests

9.0 Flight SCSs
