Sequencer Site SIRTF IOC Activity c. 2002

CAID: MIPS-924 Title: Routine 160 um Flux Standard
 
System: MIPS Principal: dhines Deputy: cengelbracht, dfrayer, SStolovy
Objective:   
Flux Calibration to be done at the beginning 
and end of every campaign after instrument 
checkout and calibration has reached a 
certain level.  This task is repeated 4 times 
with different STIM flash amplitudes to test for 
linearity in the transfer from DN/s to Jy on the 
sky.
 
Description: 
Same basic procedure as MIPS 920, but with 
stars bright enough to get 25:1 on the 
photosphere at 160.

160 um flux standard - 11 min 
Total - 11 min
Ph/SR AOT used for all observations.

This will be repeated 3 more times but before 
each repeat, an IER will execute to change the 
STIM flash amplitude for that AOR.
