The FOS time resolved mode permits data also to be line_5: obtained as a function of pulse phase for X-ray pulsars, especially in the UV, line_6: where the strong resonance lines are available. ! ! end of abstract general_form_proposers: lname: BEAVER fname: EDWARD inst: UC, SAN DIEGO country: USA ! lname: BURBIDGE fname: E.

This requires line_6: 3 synchronous restarts (one per visit) to be manually line_7: scheduled (as per conversation with Don Chance of 12/26/91). line_8: Note that the individual visits do NOT need to be synchronous line_9: with respect to each other - but synchronicity IS required line_10: between the exposures in a single visit. line_12: The PERIOD mode observations are NON-INT in order to assure line_13: that the 2 exposures occur without interruption of Earth line_14: occultation or SAA passage (i.e. the target acquisition in line_15: orbit 1, and the science observation in orbit 2). ! question: 7 section: 1 line_1: Data reduction will be performed at the ST ScI, and the analysis will be line_2: performed using FOS IDT computer facilities. ! question: 8 section: 1 line_1: HZ Her is known to have unstable periods, but require line_2: observations at certain specific phases. The binary search line_3: times were determined for the faintest mag of each target as line_4: listed in the target list.
