Task Outcome Summary

Abstract

This task collects 2, 10-DCE RAW exposures, one just before and one just after a 24 µm thermal anneal. Diagnostic data is collected during the anneal to monitor instrument temperatures. The task then performs the state transitions Observe --> Ready --> Operate (i.e. MIPS off), and then Operate --> Boot --> Off. The successful completion of the transition was confirmed by the lack of any unexpected errors during the state transition. The thermal data from this task were nominal and are presented in the metatask mips-2050. The pre-anneal and post-anneal science data show no significant change in array behavior due to cosmic ray exposure.

Analysis

We converted the diagnostic data from the thermal anneal into temperatures and generated temperature plots. These data are compared to the temperature curves from previous anneals. These data are presented in the metatask writeup mips-2050.

We compared the RAW data taken before and after the thermal anneal to look for changes in array behavior. The items of interest were the ramp starting points, the noise levels on the detectors, and the responsivity patterns. The ramp starting point data are presented in the metatask writeup mips-2060.

The data were reduced using mips_sloper with no flags. The PreFlight dark, flat, droop correction, bad pixel mask, and linearity corrections were used. We used the IRAF task qphot with an extraction radius of 6 pixels, with a sky annulus of inner radius 8 pixels and width 5 pixels. This gave us measurements of the mean sky level and of the sky-subtracted flux within the extraction radius. These results are presented below.


Results

Temperature Plots from Anneal

The temperature behavior during the anneal was nominal. The temperature plots can be found in the writeup for MIPS-2050.

24 µm Voffset Values

The pre- and post-anneal starting points for the data ramps were determined and are presented in the writeup for MIPS-2060.

24 µm Responsivity

A star was present in the field during the running of MIPS-990. The sky and source brightnesses are presented below:

There are no obvious changes in the sky or source brightnesses following the thermal anneal. Any changes are smaller than the DCE to DCE variation.


Conclusions

This campaign is about 4 hours long. There are no obvious changes in array behavior due to cosmic rays that can be seen in this data set.
