Abstract The WIYN Observatory's One Degree Imager (ODI) project has completed the initial construction phase by populating a partial focal plane, referred to as pODI. This first milestone of the larger project provides a core imaging area of 24 arcmin x 24 arcmin, along with four 8 arcmin x 8 arcmin regions offset from the core area. The 0.11 arcsec pixels provide good sampling for WIYN's often excellent seeing. Astronomers at each of WIYN's university partners, Wisconsin, Indiana, and Yale, as well as observers at other institutions using national access time provided by NOAO, have observed with pODI in support of a variety of investigations. The subjects of the research projects include very nearby targets, such as a main belt asteroid that exhibits a tail nearly a quarter of a degree long (Rajagopal et al.). Farther away, Friel et al. are studying the effects of rotation and tidal fields on Galactic globular clusters. Examples of extragalactic projects include a wide-field, multi-color imaging survey of the globular cluster populations of giant spiral, S0, and elliptical galaxies, with the aim of investigating the galaxies' formation and evolution (Rhode et al.) and the search for low surface brightness optical counterparts to HI sources revealed by the ALFALFA survey (Salzer et al.). Two complementary pipelines, one written in IRAF and the other in python, are processing the pODI data within the Pipeline, Portal, and Archive (PPA) structure developed by Indiana University's Pervasive Technology Institute. Users are able to access the data entirely within the portal interface, or they can download the processed images to a local machine. The pODI instrument is expected to continue operations through spring 2014, at which time it will be removed for an upgrade to the next stage of the instrument. It will return to the telescope approximately 6 months later with a 48 arcmin x 48 arcmin filled field of view.
