[Aavso-photometry] NGC6811 campaign update

[arne]

I've copied all of the received CCD data onto our large file server;
there are a lot of images, but only from 12 observers.  I know more
people were participating in the NGC6811 campaign than this, so if
you have not submitted your images to the AAVSO, please do so! You
can either send us your dark and flatfielded FITS images on CD/DVD
via snail-mail, to
NGC6811 Campaign
AAVSO
49 Bay State Road
Cambridge, MA 02138

Or, contact Aaron at aaronp at aavso.org for instructions as to how to
upload them to our ftp site.

Now that the images have been placed in a single location, I'll go
through each observer's submissions, do a full star extraction and
frame calibration, and add them to an observational database.  We
can then look for variables as well as work with Steve Howell on
overlapping stars and overall statistics.  My plan is to get a
paper submitted this summer on the bright end of the NGC6811 campaign,
but I need all of the data sooner than later in order to work towards
that goal.  I also plan to give each observer individual feedback
about their datasets.

There are currently 17 variables in the region that have been
submitted to VSX, so several have been discovered beyond those
already published.  We should be able to extend this considerably
with the campaign data.
