Abstract WFPC2 parallel observations will be obtained in the Ultraviolet in a search for interesting objects. This program is designed to find extragalactic sources with near UV excesses (3000A) outside of the galactic plane and far UV sources (1600A) in the galactic plane. The primary goal of this survey is to discover sources with excess ultraviolet flux. The observing strategy is to use the WFPC2 filter which provides wavelengths slightly shorter than those available from the ground but still has the maximum available sensitivity. Ground based observations (initially the digitized sky survey plates) at longer wavelengths will be used to estimate the colors of objects and (for the single exposure instances) to discriminate between sources and cosmic rays. This program is intended to fill those WFPC2 parallel opportunities which are not selected by the TAC approved parallel programs. These data will be placed immediately into the Hubble Data Archive. ------------------------------------------------------------------------------------ 7786( 1) - 07/23/97 15:30 - [ 2] Observations Description ------------------------ High galactic latitude (bII greater than 10 degrees or bII less than -10 degrees) Single orbit (non-split) F300W exposure using maximum available time Single orbit (split-able) F300W exposure CR-SPLIT=0.5 using maximum available time Two orbits (each non-split) F300W exposure in each orbit of maximum available time Two orbits (each split-able) F300W exposure CR-SPLIT=0.5 using maximum available time (orbit 1) F606W exposure CR-SPLIT=0.5 using maximum available time (orbit 2) Two orbit (one split-able, one non-split) F300W exposure using maximum available time (non-split orbit) F300W exposure, F606W exposure (split-able orbit: longer part to F300W) Three or more orbits Two or more orbit F300W non-split exposures One orbit F606W exposure (CR-SPLIT if possible) Low galactic latitude (-10 greater than bII less than 10 degrees) Single orbit (non-split) F160BW exposure using maximum available time Single orbit (split-able) F160BW exposure CR-SPLIT=0.5 using maximum available time Two orbits (each non-split) F160BW exposure in each orbit of maximum available time Two orbits (each split-able) F160BW exposure CR-SPLIT=0.5 using maximum available time (orbit 1) F814W exposure CR-SPLIT=0.5 using maximum available time (orbit 2) Two orbit (one split-able, one non-split) F160BW exposure using maximum available time (non-split orbit) F814W exposure, F606W exposure (split- able orbit: longer part to F300W) Three or more orbits Two or more orbit F160BW non-split exposures One orbit F814W exposure (CR-SPLIT if possible) Real Time Justification ----------------------- Calibration Justification ------------------------- Additional Comments ------------------- This program is being initiated at the request of the STScI Directors office (memo from Pete Stockman).
