Exposure nubmbers shown should match your delivered data files. FES Science Exposures at the end of observations are also shown on this bar. FUV obserations cease during these periods. An indicator of the SAA model in use is also given. If nothing is present on this line, the target was in the Continuous Viewing Zone.
Bars effectively indicate when the target is being viewed during orbital night.
Blank regions are orbital day. Bars on this line indicate the positions of any ground station passes that occurred during the observation period. Return to the MPS Plots page, or Return to the FUSE home page.
