V3.5 Low-Frequency Responsivity Maps [Feb & Apr 2010 ops data] |
|
o The purpose of a Low-Frequency (LF) responsivity map is to quantify
the relative spatial throughput variation over the focal plane from the
entire optical train. This includes surface brightness variations
induced by distortion, i.e., from the non-uniform convergence and
divergence of light rays, optical aberrations, and residuals from
improperly characterized PSFs over the focal plane.
o These products complement the High-Frequency (HF) pixel-to-pixel
responsivity maps, which mostly emphasize detector pixel-to-pixel
gain variations. Some LF component may also be present. The LF maps
emphasize power at spatial frequencies characteristic of the WISE
beam convolved with a grid whose size is determined by the number
of available photometric measurements. The LF maps are derived
from profile-fit photometry off level-1b frames which have been
corrected for detector gain variations using the HF maps. Therefore,
the LF maps may also capture residual detector-gain variations not
removed by the HF maps.
o If the LF spatial variations are significant, i.e., enough to impact
photometric sensitivity and repeatability requirements, the LF
maps can be applied to level-1b products in the pipeline.
o Here's a brief outline of the method:
1. query profile-fit photometry from L1b frameset mdex tables using a number
of constraints (see summaries below for band-specific constraints);
2. perform source matching across all scans and in-scan frame overlaps.
All multiple apparitions of the same sources are grouped;
3. for each group of multiple apparitions, compute the average flux
of the group and normalize each apparition flux by this average.
This ratio therefore becomes a "residual" relative to the average
of all apparitions. Only groups where the number of multiple apparitions
exceeds some minimum are considered. See below for these thresholds.
4. bin the residuals over an N x N grid on the array and increment
ancillary arrays to record their number per bin, accumulated sum,
and RMS's for final average and uncertainty estimation.
5. repeat steps 3-4 on all groups from the master match list in 2.
6. compute the responsivity and metric from the final accumulator arrays.
The relative responsivity per bin is the average of all residuals
therein.
7. optionally smooth the responsivity maps and ancillary products
(using a low-pass Gaussian filter) to remove/reduce their
"blocky" appearance.
o Overall, the LF responsivity variation for W1 & W2 (the central 95% of
the pixel distribution) is ~ ±1.5%, with an accuracy of <~0.05%
(S/N > 2000). For W3 & W4, the LF responsivity variation is ~ ±3%
with an accuracy of <~0.23% (S/N > 400).
o The LF residual maps are in general qualitative agreement with the
bright-star PSF variance maps on the Survey PSF Page, most notably at
the corners and edges.
o The results below used data from ~440 scans processed with WSDS v3.5.1
(used for the preliminary release) within a radius of 14 degrees of the
South Ecliptic Pole, and separately for two periods in the mission:
the first 20 days of February, and the first 25 days of April 2010.
There are no significant differences in the LF maps from these two
periods.
The metrics below are for the Apr 2010 run since it used more data (25 days worth), compared to 20 days for the Feb 2010 run. JPEGs of the LF responsivity and uncertainty maps for all bands are shown further below.
