The 1.3-m (ex-2MASS) Telescope


The 1.3-m is one of the CTIO small telescopes being operated by the SMARTS II Consortium. PLEASE NOTE!

See THE SMARTS 1.3m WWW PAGE for the latest news and other useful information!

Here is an exposure time calculator for the 1.3-m + ANDICAM.

Instrument Details Proposal Preparation Data Product Info

The 1.3-m telescope is run in queue mode, with observers provided by SMARTS. The instrument is a permanently-mounted, dual-channel, optical-IR imager called ANDICAM, built at Ohio State by a group led by Darren DePoy. Note that due to the final pixel scale, from 2003B all IR data is taken in 2x2 binned mode (no option) aand 2x2 binning is recommeded for the CCD data too.

Andicam was operated in queue mode on the 1.0-m (YALO Consortium) with the optical detector since the 1998B semester. The IR array was installed in July 1999, enabling simultaneous optical and infrared imaging, including dithering in the IR channel while the optical channel integrates. Please check the Ohio State Instrument News webpage and the following links for the most recent instrument news.

Nick Suntzeff's data reduction webpage contains useful hints on ANDICAM data reduction as well as measured color terms. Note that this information comes from when ANDICAM was used on the YALO 1.0-m.

Proposals for observing time should be submitted using the standard NOAO observing form, and will be evaluated in the same way as all other proposals submitted to NOAO. Since the 1.3-m telescope provides a queue/service/ target-of-opportunity observing capability not available on most other CTIO telescopes, preference will be given to (a) proposals for synoptic programs where a few frames per night will yield significant scientific benefits, or (b) proposals which require < 10 hours observing time total. Programs which require a large fraction of a given night are strongly discouraged and should be carried out at the 0.9m telescope in the "classical" observing mode.

The requested amount of observing time should be given in minutes per night and has to include an estimate for the overheads (readout: ~80 sec for a single 2048x2048 CCD image; slew to target and acquisition: ~3 minutes per target).

Once a project has been approved for observing, the PI needs to submit a detailed "Phase II" observing plan to the queue manager. This plan consists of a set of observations to be carried out, each "unit" observation of which is described by one or more data-acquisition template files. The observing plan has to be created by following the instructions for the "Phase II" Preparation & Electronic Submission forms.
