Patching some changes i haven't committed on another machine

good practice to destroy the precip rastersand report the results as the
aligned components.  otherwise could crash halfway through and we
wouldn't have the precip ready to go but the task would think it was
done.
more runtime error patches

need to get the basename of the filename for the CSV header and the
nodata value is now comfortablly nested inside the band because i
patched the data on disk.
