****************************************************** PR # 97 This a program of six pointings at the supernova remnant Puppis A. Its goal is to spectrally map the entire SNR using the SIS. Stronglines of O VII, O VIII, Ne IX, Ne X, Mg XI, and Si XIV are detectable from this remnant (as indicated by the calibration observation),and the BBXRT spectral mapping indicate strong changes inrelative line strengths across the remnant.Calibration goals include: measuring the SIS spectral resolution below 2 keV;verification of pulse height to energy conversion; calibration of effectivearea by cross calibration with previous spectral and imaging observations;comparison of faint and bright mode data for a source filling the field of view. ******************************************************
