/* ** ** Swift/XRT hardness ratio for 3C 273. ** 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 57582.643998 0.000312 0.38465 0.06414 0.97222 0 2.92777 0.25505 2.47732 0.21580 1.12618 0.16013 0.94937 0.13499 57582.645381 0.001071 0.49897 0.04375 0.98378 0 2.58711 0.13239 2.19247 0.11219 1.29090 0.09191 1.09410 0.07789 57582.647467 0.001016 0.52302 0.04596 0.97436 0 2.62295 0.13511 2.22405 0.11456 1.37186 0.09767 1.16448 0.08290 57582.649258 0.000775 0.40049 0.04219 0.95896 0 2.93518 0.16569 2.48023 0.14001 1.17551 0.10457 0.99213 0.08825 57582.651136 0.001102 0.47587 0.04117 0.97900 0 2.64325 0.13101 2.25160 0.11160 1.25785 0.08919 1.07158 0.07598 57582.653309 0.001071 0.44529 0.03863 0.97027 0 2.90592 0.14034 2.46833 0.11921 1.29398 0.09326 1.09722 0.07908 57582.654958 0.000579 0.40444 0.05115 0.97500 0 2.68696 0.18352 2.27467 0.15533 1.08670 0.11566 0.92250 0.09816
