CCD News (1Mar94)
(from CTIO, NOAO Newsletter No. 37, 1 March 1994)

ARCON has now become the principal CCD control system at CTIO.  There
are three ARCON systems in routine use, controlling Tek 1K and 2K chips
and a Thomson 1K CCD.  From November 1993 to January 1994, these three
ARCONs were used for 181 of the 253 telescope-nights during which CCDs
were used.  This represents 72% of the CCD use on Tololo during this
period.

Work is now underway to bring a second Tek 2K and a Loral 3K CCD under
ARCON control.  Both chips should be operational by the beginning of
the second semester 1994.  Two more CCDs, a STIS 2K and a Loral 1K, are
expected to come on line under ARCON control during the second half of
1994.  This should bring the use of ARCON- controlled CCDs to above the
95% level by the end of 1994.

On the software side, regions of interest and binning are now
supported.  All operation is now via the ARCON IRAF user interface,
which has been augmented to incorporate control of the 4-m R-C
spectrograph.  Users are reminded that the latest copies of the ARCON
software and instrument manuals are available by anonymous ftp (see
Newsletter No. 35, p.16, for a summary of what is available in the CTIO
FTP archives).
