/* ** ** 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 58247.241709 0.000489 0.35568 0.05792 0.97041 0 2.07228 0.17218 1.75477 0.14580 0.73707 0.10322 0.62299 0.08724 58247.242707 0.000509 0.39534 0.06632 0.98864 0 1.72763 0.15586 1.45772 0.13151 0.68300 0.09660 0.57567 0.08141 58247.243743 0.000527 0.31090 0.05087 0.98352 0 2.10277 0.16998 1.79122 0.14479 0.65376 0.09301 0.55664 0.07919 58247.244819 0.000544 0.33050 0.05523 0.96809 0 1.91372 0.15946 1.63045 0.13585 0.63248 0.09163 0.53877 0.07805 58247.245803 0.000440 0.41776 0.07181 0.98684 0 1.84532 0.17325 1.57295 0.14767 0.77091 0.11101 0.65722 0.09463 58247.246758 0.000515 0.35682 0.05888 0.97191 0 1.90182 0.16174 1.62215 0.13795 0.67861 0.09597 0.57900 0.08188 58247.247774 0.000501 0.37327 0.06224 0.96532 0 1.87498 0.16302 1.59902 0.13903 0.69987 0.09957 0.59664 0.08488 58247.248772 0.000498 0.40040 0.06741 0.98837 0 1.72859 0.15792 1.47163 0.13445 0.69212 0.09788 0.58922 0.08333 58247.249710 0.000440 0.32351 0.05313 0.98026 0 2.43438 0.19964 2.06641 0.16946 0.78756 0.11205 0.66872 0.09514 58247.250633 0.000483 0.37384 0.06271 0.97605 0 1.92283 0.17088 1.63260 0.14508 0.71882 0.10227 0.61128 0.08697 58247.251949 0.000833 0.39174 0.04842 0.98264 0 1.95946 0.12873 1.66681 0.10951 0.76759 0.08037 0.65274 0.06834
