Commissioning of the partially populated One Degree Imager (pODI) in static mode is essentially complete, and commissioning of the coherent guiding mode is underway. We should have several months of normal operations under our belt before the 2014A semester starts, but we cannot currently guarantee that all aspects of the instrument, including pipeline processing, will be fully tested and optimized. Therefore, (1) observers should be prepared to confirm the measurements they make (surprising results, especially), (2) some functions may not yet have been implemented, and (3) some aspects may be inefficient. Information about proposing for pODI as well as its capabilities and performance can be found within the ODI Observing Information web pages.
It is anticipated that pODI will be available for only the first part of the 2014A semester, after which it is expected to be removed for an upgrade to a larger 48 arcmin X 48 arcmin imager. As of this writing, pODI is scheduled to be removed in late April, 2014. Barring any delays, pODI will not be available for use after May 1st 2014. Note well that this may change, so please re-visit this WIYN current status webpage as needed.
There are several key things to note about the availability of the other 3.5-m instruments in 2014A:
Remote observing at WIYN is now available to all qualified observers (see the remote observing policies). Those wishing to observe remotely with ODI must do so from a pre-approved (and tested) workstation. More information can be found on the WIYN Remote Observing page.
WIYN is anticipating the delivery and commissioning of the Half Degree Imager (HDI) camera on the WIYN 0.9-m telescope during fall, 2013. Through the NSF Program for Research and Education with Small Telescopes (PREST), the 0.9-m Consortium will be offering nights to the community through proposals to NOAO. In semester 2014A, these nights will be offered as shared-risk, and the total number of nights available is currently under negotiation. Because of this and the schedule uncertainty as of this writing, we strongly recommend that you re-visit this WIYN status web page to get the latest updates and links to current information prior to proposing. If HDI is unavailable for part of 2014A, we anticipate continuing to offer the S2KB imager during that time.
