资源简介：
This calibration proposal measures light scattered by the G230LB grating paired with the CCD detector on STIS. The improvement will have immediate impact on the fidelity of the Next Generation Spectral Library. The observational scheme is to observe three stars of differing temperature in two similar modes CCD+G230LB and MAMA+G230L. Because the MAMA is mostly insensitive to red light comma only the CCD spectra will show the scattered light problem. The scattered light will be modeled and applied to the NGSL. In addition comma the dependence of scattered light on the position of the star relative to the centerline of the slit at the time of exposure will be measured.
