		| Abstract: | 
		This contribution describes the “spectro-perfectionism” algorithm
 of Bolton & Schlegel (2010) that is being implemented within the
 Baryon Oscillation Spectroscopic Survey (BOSS) of the Sloan
 Digital Sky Survey III (SDSS-III), in terms of its
 potential to deliver
 Poisson-limited sky subtraction and lossless compression of the input
 likelihood functional given raw CCD data. |
