These are scans of plates obtained at Boyden station by German
institutions, taken by Milcho Zvetkov Nov 2014.

Metadata is available from the WFPDB.

Calibration for these is a bit tricky, what with the combination of crowded
fields (Magellanic clouds!), notes on the plates, and partially high noise.

By running bin/calibrate.py once each with and without --crowded and
--no-object-filter I'd hope you can reproduce Markus' solutions.  Note that
calibrate.py takes its metadata from the WFPDB.

What we got from upstream are tiff files; these are, for now, preserved
in data/scans_244/.  The script bin/convert.py was used to convert them into
raw FITS files, stored in data/fits.  If you ever need to re-do this, exectue
it in boydende/ as python bin/convert.py.  You'll have to re-do calibration
then, too.

We also got photos of the envelopes in data/static/envelopes/.  To get to
one envelope per dataset, we used bin/envelope_cutout.py.  This is
a manual, interactive process -- the script show the photo and asks
for its plate number prior to writing them to data/static/envelopes/.
Requires a forwarded X-Server to run.  The raw 4-envelope photos are
for now preserved, too (they are the one with dashes in their names); they
are not used in the interfaces.
