Attention APO 3.5-m NIC-FPS users:

On April 1, we will implement our new policy where the raw NIC-FPS data
are automatically deleted after 90 days.  All data obtained before
Jan 1, 2008 will be deleted tomorrow!  Please download your raw
NIC-FPS data if you want them, before tomorrow.

Details of data location and access may be found in Section 6.1 of
the NIC-FPS users manual available from the main APO home page.

Here is an excerpt from the last users committee minutes (dated 2/25/08)
with information about this policy.

"With typically short exposure times and multiple raw data frames 
resulting from Fowler sampling, NIC-FPS can produce prodigious 
amounts of raw data.  Our current NIC-FPS data processing system 
returns processed frames immediately to the user, but the raw-frame 
data are kept on disk at APO, where the user can download 
them at a later time. Although we normally keep all data for 
the other instruments for approximately 9 months, we are going 
to establish a practice that purges raw NIC-FPS frames 90 days after
the observations are taken.  If NIC-FPS users are interested in 
having their raw data frames, we strongly suggest that they download 
these data not later than a few weeks after they are taken."

Please contact Bruce Gillespie or myself with questions or concerns
about this policy.
