... The absolute flux calibration of NICMOS will be calculated from observations of standard stars with known flux distributions F( ). ... In order to expand the set of IR standard stars in the appropriate flux range for NICMOS, M. Rieke, R. Thompson, and collaborators at the University of Arizona are making photometric observations of solar-analog stars, which will be used to normalize the solar spectrum to the observed IR magnitudes. ... Relative flux references accurate to 1.5% for standard...
ST-ECF Instrument Science Report ACS-2006-02 Wavelength and Flux calibration of the ACS/SBC PR110L and PR130L prisms S. S. Larsen, February 2006 ABSTRACT Wavelength- and flux calibrations are presented for the ACS/SBC PR110L and PR130L slitless spectroscopy modes. ... Wavelength. ... Flux calibration Figure 5: Comparison of sensitivity functions for the SBC prisms derived from the inorbit calibration (solid curves) and the ground calibration from Bohlin et al. 2000 (dashed curves). ...

... The science from both these missions contributed to three of the Nobel Prizes Giacconi (2002), Mather, and Smoot (2006) - awarded for NASA-based science. ... We encourage NASA to seek new launch capabilities to fill this strategic gap in moderate lift rockets to enable the Explorer program to continue launching missions with significant science payoff but reduced costs and timescales compared to large strategic missions. ... 18 Appendix B: Explorer Missions 1989-present (From PILMSS) No . ...
