These are the "Kapteyn series" plate scans.  The files were scanned and
provided my Milcho Tsvetkov, <milcho.tsvetkov@gmail.com>.

Markus synced them here 2012-07-23 using the command line

env RSYNC_RSH="ssh -p2222" rsync -av astrodata07.gac-grid.org:/store/01/aip/digitplates/POT015_KS_FITS data/incoming

-- the remote server accepts msdemlei@alnilam's ssh pubkey.

The files in incoming include rotated scans (_r.fits).  We ignore these
for now.

The incoming images were not in a good shape, frequently being FITS-invalid,
and they've not been cut out.  They were processed into what's in data/fits
(our actual data files) using bin/fix_incoming.py.

In 2014, Milcho Tsvetkov has visited ARI, and further work was done on those.
Milcho came up with the .coutout.txt and .observed.txt files in res, and
he brought in the low-res color scans in data/static/jpegs as well as the
data/static/wedges.


The test data was obtained by simply pulling in the metadata from
alnilam using copyTableFancy:

copyTableFancy.py kapteyn/q#main kapteyn.main

For datalink testing, we additionally need a cutout of POT015_000317.fits
and some data in static.  As Markus.
