WFC User Notes and Performance

During the spring of 1998 the Wide Field Camera with four thinned EEV 4kx2k CCDs was commissioned at 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 INT Wide Field Survey programme began in August 1998 and this page provides status information for the survey and a gateway to access the survey data.

Dates of the scheduled observational periods 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 been acquired.

Under the terms of the Announcement of Opportunity the raw 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 ( jrl@ast.cam.ac.uk ) for password access to the data.)

In order to obtain access to the survey data, users 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. Registration requests will only be processed during the working day (GMT), subsequent data requests will be available at any time.

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 size.

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 explanatory notes are available.

We ask that authors using this data employ the standard acknowledgement in their papers.

Further details may be obtained from the WFC instrument specialist, Dr. N.A. Walton, naw@ing.iac.es , or the WFS project leader Dr. R.G. McMahon. rgm@ast.cam.ac.uk
