Sequencer Site SIRTF IOC Activity c. 2002

CAID: MIPS-085 Title: CSMM Scanpos Table Upload
 
System: MIPS Principal: dmkelly Deputy: alberto
Objective:   
Upload a new version of the MIPS Scanpos 
table
 
Description: 
The MIPS Scanpos table is a block of global
variables that is used to define a set of 
standard
pointings for the MIPS scan mirror. This block 
is
addressed using the CESCANPOS 
command.  This table
includes several positions that might need
updating during IOC, including SED Nominal 
Start,
70um NFOV Nominal, 24um Dark, 70um Dark 
1, 70um
Dark 2, and 160um Dark.  The purpose of this 
task
is to upload a new version of the Scanpos 
table.
