17.5 The Cycle 8 calibration plan was modeled closely on the Cycle 7 calibration plan. Once again, supported modes were monitored for such things as sensitivity changes, flat-field evolution, and dispersion solutions. No additional calibrations were taken for most available-but-unsupported configurations.In addition to monitoring instrument health and safety and maintaining the overall calibration of STIS supported modes, our special goals were as follows:
6: To characterize observations with the FUV-MAMA repeller wire turned off, with the aim of possibly making this available for Cycle 10. This should improve the spectral resolution at the expense of a ~35% loss of sensitivity.
