3.0 Instrument Status and Science Support
3.1 Flight Events and HETG Instrument Status
The HETG continues to function with no outstanding issues.
There were 3 HETG observations in September including a Capella calibration observation, obsid 5040, and our GTO observation of 4U 1957 which shows a bright continuum.
3.2 Science Support to CXC, SWG, etc.
Added 3 more data points to the HRMA FWHM monitoring plot, see plot next page.
The new adjustments to the ACIS geometry have been completed and a slight change (0.0135 %) to the MEG grating period is also proposed to bring the HEG and MEG wavelength scales into precise agreement, see http://space.mit.edu/HETG/technotes/chip_gaps04/chip_gaps04.html .
4.0 GTO Science Program
4.1 Observations and Data status
A list of all HETG GTO observations and their status to date is given in Appendix A.
