Segev BenZvi just noticed that the random offsets generated and saved by doc/nb/DESI-0347_Throughput.ipynb only cover a square region that is 1.6deg on a side (due to my confusion between field-of-view and cone opening angle). This issue is to update the notebook and re-make the 3 sample realizations (which live in the svn repo for this package).

For reference, specsim interpolates random offsets from these files using scipy.interpolate.RectBivariateSpline, which appears to silently return the closest grid point when asked to extrapolate (although I can't find this documented anywhere).
