progress on Tspec reduction

[Mike Cushing]

Hello All,

So last week I was able to hide away and code without interruption. I
made some good headway on Tspec reduction code.

I was able to:

1) Construct a 2D wavelength and spatial position wavelength
calibration robustly.

2) Use Bsplines to subtract the background. This worked very well on
pair subtracted images as the OH lines are much reduced, but less well
on a single image. Still working on this.

3) Extraction the spectrum using polygon clipping (see Smith et al.
2007, PASP, 119, 1133 if you are interested).

There is still much to be done, not the least of which is getting all
of this into Spextool. But given that we will be using Tspec to
followup WISE brown dwarf candidates, I can now commit more time to
finishing the modifications.

Things still to be done:

1) Construction spatial maps to be used in optimal extraction and bad
pixel fixing (in the sum extraction case)

2) Include all of this in Spextool and make it user friendly and user
proof.
