All targets will be observed with the line_4: FOS/RD and the low dispersion grating G160L to see if they have enough flux at line_5: short wavelengths to be used as probes of the line-of-sight medium in the far line_6: ultraviolet. line_7: Cycle 1 (1-6 months, SV)=Exposures 5,6,16,17 line_8: Cycle 2 (7-18 months)=Exposures 1,2,3,4,7,8,9,10 line_9: Cycle 3+4 (19-30 months)=Exposure 18 line_11: Parallel observations should be scheduled only if primary observations are line_12: taken in dark time.
