Calibration of MIPS Stimulators Against Celestial Sources at 70 and 160 um |
|

|
Objective: |
|
Measure the output of the MIPS stimulators against the output of known stars. |

Description: |
|
|
Scan maps will be made of standard stars with stimulator flashes interspersed. |

Stimulator calibration at 70 and 160um |
|
|
|
|
|
|
|
|
|
1)Make a scan map where a standard star is observed in both forward and |
|
|
|
|
|
|
|
|
reverse scan directions using medium scan speed. Use 3 second exposures. |
|
|
|
|
|
|
|
|
A scan will be 30' in length so that 2 stim flashes should be recorded in a given direction. |
|
|
|
|
|
|
|
|
2) Repeat five times. |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Place in Schedule: |
|
|
After aperture door is opened. |
|
|
|
|
|
(relative to water shed events) |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Required Conditions: |
|
|
MIPS detector aliveness tests must have been performed. |
|
|
|
|
|
|
|
|
Must be able to place a star in the width of a scan (5'). |
|
|
|
|
|
|
|
|
Backgrounds must be less than the equivalent of 200,000 photons/sec at 160um: |
|
|
|
|
|
|
|
|
|
160um <= |
1.10E-07 |

One forward/back scan genreates 344 DCEs between the two arrays. |
|
|
|
|
|
|
|
|
A total of 1720 DCEs are generated in the complete test. |
