/* ** ** 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 54885.149017 0.000524 0.42161 0.05428 0.83978 0 3.36405 0.23457 2.84881 0.19857 1.41832 0.15351 1.20064 0.12994 54885.350266 0.001019 0.46065 0.03947 0.97159 0 2.97077 0.14185 2.53003 0.12080 1.36849 0.09736 1.16532 0.08290 54885.352344 0.001059 0.43335 0.03697 0.96995 0 3.08346 0.14459 2.58404 0.12116 1.33621 0.09521 1.12114 0.07988 54885.354060 0.000657 0.37069 0.04216 0.96476 0 3.15483 0.18526 2.64714 0.15544 1.16945 0.11392 0.98251 0.09569 54885.355665 0.000949 0.49113 0.04281 0.99085 0 2.97779 0.14952 2.49658 0.12536 1.46248 0.10421 1.22463 0.08725 54885.357141 0.000527 0.42553 0.05494 0.95055 0 2.80060 0.19560 2.32602 0.16246 1.19173 0.12941 0.98972 0.10748 54885.359401 0.001733 0.44677 0.02985 0.97410 0 2.96744 0.10968 2.50596 0.09261 1.32576 0.07378 1.12046 0.06234 54885.422416 0.000310 0.39394 0.06549 0.97196 0 2.89703 0.25563 2.47812 0.21863 1.14127 0.16081 0.97703 0.13767 54885.423067 0.000341 0.30379 0.04916 0.99153 0 3.31692 0.25865 2.84036 0.22148 1.00764 0.14288 0.86370 0.12247 54885.423715 0.000307 0.37655 0.06287 0.97170 0 2.98556 0.26063 2.56825 0.22420 1.12421 0.16000 0.96707 0.13764 54885.425055 0.001033 0.43294 0.03701 0.97479 0 3.06685 0.14362 2.63337 0.12332 1.32777 0.09495 1.14010 0.08152 54885.427037 0.000949 0.50789 0.04418 0.98171 0 2.85299 0.14439 2.45535 0.12426 1.44901 0.10253 1.24706 0.08824 54885.428996 0.001010 0.42843 0.03634 0.97708 0 3.18562 0.14788 2.74101 0.12724 1.36482 0.09688 1.17430 0.08336 54885.431091 0.001085 0.41942 0.03565 0.98667 0 2.99201 0.13913 2.56766 0.11939 1.25491 0.08930 1.07684 0.07663 54885.433099 0.000923 0.50375 0.04424 0.99060 0 2.91372 0.14870 2.50753 0.12797 1.46778 0.10492 1.26293 0.09028
