The SMC SNR 1E0102.2-7219 as a Calibration Standard for X-ray Astronomy in the 0.3-2.5 keV Bandpass
Paul P. Plucinsky, Frank Haberl, Daniel Dewey +8
The flight calibration of the spectral response of CCD instruments below 1.5 keV is difficult in general because of the lack of strong lines in the on-board calibration sources typ…
Outer jet X-ray and radio emission in R Aquarii: 1999.8 to 2004.0
E. Kellogg, C. Anderson, K. Korreck +5
Chandra and VLA observations of the symbiotic star R Aqr in 2004 reveal significant changes over the three to four year interval between these observations and previous observation…
Discovery of Rapid Hard X-ray Variability and New Jet Activity in the Symbiotic Binary R Aqr
J. S. Nichols, J. DePasquale, E. Kellogg +3
Two Chandra observations of the R Aqr symbiotic binary system taken 3.3 years apart show dramatic changes in the X-ray morphology and spectral characteristics in the inner 500 AU o…
The Flight Spectral Response of the ACIS Instrument
Paul P. Plucinsky, Norbert S. Schulz, Herman L. Marshall +11
We discuss the flight calibration of the spectral response of the Advanced CCD Imaging Spectrometer (ACIS) on-board the Chandra X-ray Observatory (CXO). The spectral resolution and…
Monitoring the Health and Safety of the ACIS Instrument On-Board the Chandra X-ray Observatory
Shanil N. Virani, Peter G. Ford, Joseph M. DePasquale +1
The Chandra X-ray Observatory (CXO), NASA's latest ``Great Observatory'', was launched on July 23, 1999 and reached its final orbit on August 7, 1999. The CXO is in a highly ellipt…
