A 21cm sky map of a goodly chunk of the northern sky

[Marcus D. Leech]

Here's the latest version of our 21cm sky map, derived from nearly 5 
months worth of data from our 21cm spectrometer instrument.

All of the real-time processing is handled, naturally, with Gnu Radio, 
and then some Python post-processing.
