During the spring of 1997 the Wide Field Camera was commissioned
in the prime focus of the 2.5-meter Isaac Newton Telescope on
La Palma. This new instrument offers unique opportunities for the
UK/NL communities to execute high resolution, deep, wide field
optical imaging surveys.
The Wide Field Survey programme
commenced in August 1998 and this page provides the portal to access
the data sets.
Dates of the scheduled observational
give an indication of
when new data will be available for download. Flux and Astrometrically
calibrated data will be made available approximately one month after it has
Under the terms of the
Announcement of Opportunity the data is made immediately available
to researchers from the UK and NL only. The data will be released to the
wider community after the standard one year period. (Those researchers
associated with the survey applications as co-I's will need to contact
Jim Lewis ( firstname.lastname@example.org )
for password access to the data.)
In order to obtain access to the raw data, requesters must first
register. We require this information in order to be able to inform
you of when your data is ready for download and also for use in
collating access statistics.
When searching the list of observations, you may request data files
and submit your request. You will be sent an email upon completion of
that request, this will inform you of where and how you may retrieve
your data files. Please note that at present the data is only
available by ftp download from our ftp site on La Palma. Also,
requests are processed during the working day (GMT), with the data
being available for ftp download in the evening.
The processed data files will shortly be made available, further
details later in September 1998.
The present access system is a provisional one and is subject to
change. It is probable that large data requests will be distributed by
tape medium in the future and that ftp downloads may be limited in
During the April 1998 commissioning period, test data on a small
number of fields was obtained. This data is made available to the community.
This test data is currently located in
Cambridge, UK. Some brief
We ask that authors making use of this data employ the standard
acknowledgement in their papers.
Further details may be obtained from the WFC instrument specialist,
Dr. N.A. Walton ( email@example.com).
