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). MIPS299 was executed twice during Campaign R and an average of the two observations was supplied to the MIPS DAT as the Campaign R SED illumination correction.

Analysis

First raw data files: mips_AOR_7597312_sed_A70_P70S_pos1_10s.fits = MIPS299a Second raw data files: mips_AOR_7597568_sed_A70_P70S_pos1_10s.fits = MIPS299b

Reduction:

mips_sloper -j CamQ -l -q MIPS299a(b)

mips_caler -C CamQ -P mips_caler70S.param -i MIPS299a(b).red.fits

mips_enhancer -f MIPS299a(b).cal.fits -C -NA

The -NA flag in mips_enhancer normalizes the illumination correction using only side A of the 70 µm array.

Results

Two normalized SED ICs was created and are shown below. The patch of sky chosen for both of these observations was zodi_14a.

Reduced MIPS299a data normalized using side A. For image section [5:10,5:25]: Mean = 1.336, RMS = 0.484.

Reduced MIPS299b data normalized using side A. For image section [5:10,5:25]: Mean = 1.440, RMS = 0.631.

The ratio of MIPS299b / MIPS299a. For image section [5:10,5:25]: Mean = 1.084, RMS = 0.253.


Conclusions

The two illumination corrections determined in Campaign R are in resonable qualitative agreement. Significant pixel-pixel variations do exist between the ICs and between the average Campaign R SED IC and other SED data obtained in this campaign. For example, pixels [4,6] and [4,12] both have low values in the ICs that are not apparent in the data for MIPS145, resulting in two "hot" pixels in the reduced data. In other words, the SED illumination correction does not represent a time-independent correction to the undispersed stim flash illumination pattern. SED observations are likely to be limited by these residual pixel-to-pixel time-dependent variations, although an average of a large number of illumination corrections may mitigate some of these effects.

Output and Deliverable Products

This SED illumination correction has been incorporated into the Campaign R calibration files of the MIPS DAT and is the average of the two ICs obtained during the campaign (Mean = 1.388, RMS = 0.537 for the image section [5:10,5:25]).
