This is a catalogue of galaxy candidates that Carolin Wittmann did as
a part of her PhD thesis.  She did this from a stacked and mosaicked
image of the persus cluster, which we got (via a horrible dropbox-like
thing) from Ralf Kotulla <kotulla@wisc.edu>; perseus_r_fullres.fits is
what Carolin worked on, the others are more or less informational.  The
catalogue itself should be on VizieR, too, the images are exclusive to
our service.

To generate the sample perseus_r_fullres.fits, I used

from gavo.base import coords
from gavo.utils import fitstools
from gavo.utils import pyfits
import numpy

hdus = pyfits.open("/data/gavo/inputs/pcc/data/perseus_r_fullres.fits")
skyWCS = coords.getWCS(hdus[0].header)
pixelFootprint = numpy.asarray(
					numpy.round(skyWCS.wcs_world2pix([
						(49.6, 41.3),
						(49.55, 41.25)], 1)), numpy.int32)

res = fitstools.cutoutFITS(hdus[0],
(skyWCS.longAxis, min(pixelFootprint[:,0]), max(pixelFootprint[:,0])),
					(skyWCS.latAxis, min(pixelFootprint[:,1]), max(pixelFootprint[:,1])))	
res.writeto("zw.fits")
