Task Outcome Summary

Abstract

The activity determines the slit illumination by observing several sky positions in a region of high 70 µm background. The SED-mode AOT was be executed with 10 sec integration times at at several telescope positions containing no bright point sources. A median of these observations was constructed to average out spatial structure in the background. Each SED AOT provided 4 sky positions. The telescope can be moved to 4 positions using the SED mapping mode. In this case, the moves were made in the cross-dispersion direction by an amount equal to the length of the slit (about 4.5 arcmin; this is the maximum offset allowed in the SED mapping-mode AOT).

Analysis

Raw data file: mips_AOR_7341824_sed_A70_P70S_pos1_10s.fits = MIPS299

Reduction:

mips_sloper -j CamO -l -q MIPS299

mips_caler -C CamO -P mips_caler70S.param -i MIPS299.red.fits

mips_enhancer -f MIPS299.cal.fits -C


Results

A normalized SED IC was created and is shown below. The patch of sky chosen for these observations was zodi_13a. Of note is the flux deficit observed in columns 17 and 18 of the array. Also, the number of "hot" and "cold" pixels in the illumination correction has been reduced significantly, with many of these pixels appearing at the edges of the array.

Conclusions

An SED IC can be constructed with the AOR used in this task. The difference in the noise levels between sides A and B is less than in illumination corrections determined in Campaigns I and K. Also, the noise level of this IC is less than the previous ICs obtained in earlier campaigns. This suggests that adjusting of detector parameters such as the bias level is mitigating some of the noise problem encountered on side B and optimizing the performance of side A.

Output and Deliverable Products

The SED illumination correction has been incorporated into the Campaign O calibration files of the MIPS DAT.
