Abstract

We have constructed a 70micron NARROW FIELD IC. The standard deviation of the narrow-field 70micron IC over the entire array is approximately 33% for a total of 170DCEs, but this statistics includes the illumination pattern of the 70micron array. If we remove the illumination pattern by ratioing two ICs of 85DCEs each, we find that the rms is approximately 15%.

Analysis

We have observed a 70micron narrow-field photometry cluster-target AOR with 3 second DCEs and 6 pointings in a rectangular pattern (2x3, with 300 arcsec offsets) for a region of sky free of bright 70micron point-sources. This task was executed twice in Campaign I for a total of 170DCEs.

We used mips_sloper with sensitive cosmic ray detection (-q option) turning off the electronic non-linearity correction, mips_caler (using the 70micron dark me_70_darka_CamH_22oct2003.fits) and mips_enhancer with the following options:

mips_enhancer -OD -i listof70ic_NF.lst -SC 3 -C -dn -NI -FD -o ic70_NF_campaignI -r 1

Note that we rejected the first DCE after the stim flash (-r 1 option) and normalized the input images (-NI option).

The regions of the sky observed were:

zodi_12b (RA=7:37:31.5146 and Dec=27:35:20.6376, J2000) with a predicted brightness at 70microns of 14.3MJy/sr, and
zodi_28a[315] (RA=21: 5: 7.4259 and Dec= -21:54: 4.3864, J2000) with a predicted brightness at 70microns of 13.9MJy/sr.

The predicted values of the 70micron brightness are from SPOT for the date of the observing (Oct 16, 2003).

Results

The NF 70micron IC constructed combining a total of 170DCEs is shown in Figure1. Statistics on the images provides the following:

2 regions (170DCEs):mean= 1.01074; median= 0.99001; sdtdev= 0.32654; skew= 0.33925;
SCAN zodi_12b (85DCEs):mean= 1.02242; median= 0.99324; sdtdev= 0.31689; skew= 0.40657;
SCAN zodi_28a (85DCEs): mean= 1.00690; median= 0.99022; sdtdev= 0.35040; skew= 0.23549.

The histograms are shown in Figure2. Note that the statistics is better when only using region zodi_12b because this region is brighter.

Figure2. Histogram of the 70micron Narrow Field Illumination Corrections observed in CampaignI for two different regions of the sky, and both regions combined.

A better way to assess the quality of the observed ICs is to remove the illumination pattern of the 70micron array. To do so, we ratioed different 70micron IC. The statistics on the images provides the following:

ratio of 2 NF 70micron ICs (85DCEs each): mean= 0.96129; median= 0.97913; sdtdev= 0.14511; skew=-1.35372.
