Monitor the wavelength calibration - dispersion solutions for representative wavelength settings of the STIS MAMA. Internal wavecals will be obtained at primary and secondary central wavelengths for all the MAMA gratings -- chosen to cover both Cycle 29 usage and settings observed in previous monitoring programs (for long-term monitoring). Most of the settings in this program use the LINE lamp (for a total of approximately 1.5 hours) two of the shortest wavelength settings use the somewhat brighter HITM2 lamp comma however. All but one setting will use a lamp current of 10 mA.
