0707 distortion maps

beam locations & peak fluxes
The results of my distortion mapping work below. Note that, especially for 06, there are a LOT of cases where no beam locations correction (noBL) had a higher peak than the distortion corrected map. I have no explanation for this yet. More work to come...

sign errors
pinned down the problem. Was a minor sign error in the offsets. Why is it that simple sign errors are ALWAYS the hardest things to track down? Now, open question: should x,y scaling be free parameters or not? What I mean is, when I measure the positions of bolometers on the array using the planet map, should I allow the X and Y stretch (the bolometer spacing) to change? Should it be a uniform stretch in X and Y or should it be allowed to 'distort' too? My opinion is, none of the above: I'm measuring their actual positions (in terms of a fixed spacing) and therefore stretching or distorting to match the nominal positions is not necessary.

distortion mapping failures
So, despite the fact that I clearly have a distortion mapper working, applying the distortion maps that come out of it do NOT improve the peak or FWHM of the data.
filling factors
to do: histogram per square degree, plot cumulative > some bin number (100 mJy, 300 mJy, 1 Jy) vs l, then do it again for b=+/-.1, +/-.3.
distortion mapping
Between sign errors, failures to fit, and.... I really don't know WHAT was going on, I finally figured out how to get the cursed distortion mapping to work. I still haven't even started testing, unfortunately. I don't know why I can fit the way the OP did, fitting R and Theta, and I apparently can't fit x,y. It's frustrating.
Flagger images
James requested sample images from the flagger for the methods paper. Below are images + description: .. image:: http://3.bp.blogspot.com/_lsgW26mWZnU/SXHsZcqegtI/AAAAAAAAEs4/3PjUtU2IXtQ/s400/sample_waterfall_070911_o15_highFnoisepng.png This is a "noise-dominated" scan in the sense that the high/low pixels are set by noise, not signal. Despite the clear high frequency noise, this image actually maps out pretty well - I think the high-noise bolometers get downweighted and the high/low pixels probably get clipped by my hot pixel rejection procedure. .. image:: http://3.bp.blogspot.com/_lsgW26mWZnU/SXHsY7Rgq3I/AAAAAAAAEsY/0NT8IB26JUo/s400/flagger_marked_source_050708_o15.png An image of the galactic center with a source southeast of center identified. .. image:: http://1.bp.blogspot.com/_lsgW26mWZnU/SXHsYyHCEGI/AAAAAAAAEsg/3iwoklY0--0/s400/sample_waterfall_050708_o15_glitchandsources.png A scan from the GC image above.

0709 rotators fixed, latest run
0709 11-13 needed to be 83.88 degrees, they're all fixed now. I flagged the l060 070911 maps; I'm not convinced that was weather, there were some fluctuations up to 2400 Jy! Maybe a cloud would do that though.
Problems in the latest run:

the l060-l062 range has some severe noise problems and rotator issues. They need to be fixed before release.
