| Abstract: |
Beginning in mid-2007, the XRT images are marred by dark spots due to
beads of congealed contaminant. While programs are available for
improving the cosmetic appearance of the images, no method has yet
been demonstrated for a quantitative correction. We have employed a
flatfielding method developed for MSU's MOSES sounding rocket payload,
in an attempt to restore capabilities for quantitative photometry in
the affected pixels. Initial results are encouraging;
characterization of the uncertainties in the photometric correction
are ongoing. We report on the degree to which this flatfielding
attempt has been successful. |
