/* ** ** Swift/XRT hardness ratio for B2 1811+31. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 59156.832035 0.001293 0.20332 0.05069 0.96629 1 1.78088 0.18297 0.44904 0.04613 0.36210 0.08225 0.09168 0.02082 59156.834911 0.001583 0.17506 0.04276 0.94495 1 1.73616 0.16361 0.44003 0.04147 0.30394 0.06850 0.07711 0.01738 59156.837933 0.001438 0.19126 0.04665 0.96970 1 1.72751 0.16829 0.43592 0.04246 0.33041 0.07388 0.08333 0.01863 59156.840199 0.000828 0.31853 0.08352 1.00000 1 1.71622 0.22487 0.43417 0.05689 0.54666 0.12415 0.13832 0.03142 59156.842421 0.001394 0.18589 0.04565 0.95833 1 1.84320 0.17983 0.46403 0.04527 0.34262 0.07721 0.08633 0.01945 59156.845515 0.001699 0.25034 0.05203 0.94350 1 1.66192 0.15508 0.42028 0.03922 0.41605 0.07726 0.10508 0.01951 59156.895401 0.001699 0.18030 0.04390 0.96581 1 1.58927 0.15310 0.39074 0.03764 0.28655 0.06408 0.07080 0.01583 59156.898669 0.001569 0.24102 0.05226 0.99984 1 1.66834 0.16298 0.41345 0.04039 0.40211 0.07783 0.09949 0.01926
