STIS MAMA Dipsersion Solution Check
Abstract
Wavelength dispersion solutions will be determined on a yearly basis as part of a long-term monitoring program. Deep engineering wavecals for each MAMA grating will be obtained. Wavelength centers will be selected at extreme and central settings of each grating. Intermediate settings will also be taken to check the reliability of derived dispersion solutions. Only Prime modes have been selected for observation in this program. The purely internal wavelength calibrations will taken using the Pt/Cr-Ne {CIM} line lamp and the appropriate 2 pixel wide supported slit.
