Extreme Deconvolution of Stellar Data
-------------------------------------
Figure 6.12

Extreme deconvolution applied to stellar data from SDSS Stripe 82. The top
panels compare the color distributions for a high signal-to-noise sample of
standard stars (left) with lower signal-to-noise, single epoch, data (right).
The middle panels show the results of applying extreme deconvolution to the
single epoch data. The bottom panel compares the distributions of a color
measured perpendicularly to the locus (the so-called w color is defined
following Ivezic et al 2004). The distribution of colors from the extreme
deconvolution of the noisy data recovers the tight distribution of the high
signal-to-noise data.
