Abstract

We have constructed the 70micron Narrow Field (NF) IC. The standard deviation of the 70micron IC over the entire array is 31%, but this statistics includes the illumination pattern of the 70micron array.

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. The total number of DCEs is 132.

The reduction was performed with the DAT programs. We used mips_sloper with sensitive cosmic ray detection (-q option) turning off the electronic non-linearity correction, mips_caler (using the 70micron me_70_darka_CamP_4nov2003.fits) and mips_enhancer with the following options:

verbose = 0
scale = 1.
filename = ic70_scan
prefix = ic_scan70
nXTile = 1
nYTile = 1
dark = 0
flat = 0
illumination_correction = 1
NormalizeInput = 1
SigmaCut = 3.0
SigmaTolerance = 0.25
MaxIterations = 10
StackSTDEV = 0
OutlierMinPoints = 3
QuartileFactor = 10
OverlapTolerance = 0.5
diagonistics = 1
WriteGeometry = 0
WriteOutlier = 0
WriteTiles = 0
FluxMean = 0
FluxMedian = 1
OverWrite = 1
distortion = 0
UseBoostFrame = 1
reject = 1

Note that we rejected the first DCE after the stim flash (reject = 1 option) and normalized the input images (NormalizeInput = 1 option).

The region of the sky observed was:

zodi_29a (RA=21:49:42.1042 and Dec=-7:49:51.7263, J2000) with a predicted brightness at 70microns of 11.7 MJy/sr,

The predicted values of the 70micron brightness are from SPOT for the date of the observing (Nov 3, 2003).

Results

The NF 70micron IC is shown in Figure1. Statistics on the images provides the following:

PHOT (132DCEs) zodi_29a: mean= 0.89666; median= 0.88491; sdtdev= 0.31280; skew=-0.10727;

The histograms are shown in Figure2.

Figure2. Histogram of the 70micron Illumination Correction observed in Campaign P obtained in NF mode.

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, one made with half of the DCEs and the other with the remaining half. The statistics (mean, std, median, mode, skewness, min, max) on the images provides the following:

ratio ICs PHOT(66DCEs)/SCAN(66DCEs): 0.9951    0.1837    0.9924    1.082   -0.2316    0.229    1.48
Side A alone: 0.9843    0.1644    0.9727    1.083    0.1422    0.5338    1.45
Side B alone: 1.006    0.2004      1.01    1.064   -0.4807    0.229    1.48

The ratio of 70micron ICs is shown in Figure3.

Conclusions

We have constructed 70micron ICs obtained in NF mode using one region of the sky (zodi_29a). The standard deviation of the 70micron IC over the entire array is approximately 31%, but this statistics includes the illumination pattern of the 70micron array. If we remove the illumination pattern by ratioing two NF ICs, we find that the rms is approximately 18% (16% in side A and 20% in side B).
