NASA Exoplanet Science Institute - PTI & KI Public Data
You can get a close-up map of a region by selecting a point in red [PTI data] or yellow [KI data] on the above image, or by typing a coordinate below.
The NASA Exoplanet Science Institute (NExScI) is the science operations and analysis center for NASA's Exoplanet Exploration Program.
NExScI has made available a database of observations from the Palomar Testbed Interferometer (PTI), covering 1350 nights and 1349 targets, and observations from the Keck Interferometer (KI) visibility mode data, containing 247 science targets on 48 nights. The metadata (updated October 2007) describing these data sets can be accessed below using spatial search queries, provided by the Infrared Science Archive (IRSA). This data set is refered to as NExScI_PTI_KI. The complete data set can be accessed for registered users at the NExScI (click here to register). The IRSA metadata search query results link you to the NExScI PTI/KI database, but only if you've already logged in to the PTI and KI databases.
The NExScI_PTI_KI data coverage is represented on the all-sky ISSA image above. Catalog source positions are shown in red for PTI positions and in yellow for KI positions.
