Please mark it up as these data come in. 16555 2.8, study of the He II 304 absorption will yield information for many different studies. This observation appears to have executed as planned. Measurements of the instrumental background of both FOS detectors will be measured. The proposal will execute 12 times during cycle 5.
All exposures are internals.
All spectra are image mode. These FOS internals were not displayed, but appear to have executed as planned. The HRS will be used in an attempt to detect white dwarf companions around several barium and CH stars. This will test the theory that the abundance anomalies in these stars were caused by mass transfer from the precursors of the white dwarfs. The sequences will include moderate-sized rapid mode observations.
