/* ** ** 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 58216.294909 0.000469 0.35579 0.05891 0.98765 0 2.11332 0.18189 1.76497 0.15190 0.75190 0.10635 0.62604 0.08854 58216.295890 0.000512 0.34137 0.05692 0.97175 0 1.99328 0.16740 1.67865 0.14098 0.68045 0.09802 0.57300 0.08254 58216.296873 0.000472 0.40398 0.06867 0.97546 0 1.84178 0.17131 1.55129 0.14429 0.74404 0.10587 0.62660 0.08916 58216.297880 0.000535 0.31908 0.05215 0.97838 0 2.05884 0.16867 1.73379 0.14204 0.65693 0.09290 0.55341 0.07826 58216.298936 0.000521 0.33521 0.05566 0.97778 0 1.99507 0.16777 1.67969 0.14125 0.66877 0.09574 0.56303 0.08060 58216.299940 0.000483 0.46331 0.08019 0.98204 0 1.55583 0.15331 1.31043 0.12913 0.72082 0.10256 0.60750 0.08644 58216.300887 0.000463 0.46121 0.07977 0.98125 0 1.62462 0.15766 1.36783 0.13274 0.74930 0.10727 0.63116 0.09036 58216.301873 0.000524 0.35784 0.05904 0.95580 0 1.92500 0.16363 1.61691 0.13744 0.68883 0.09742 0.57900 0.08188 58216.302860 0.000457 0.41314 0.07048 0.97468 0 1.86606 0.17233 1.57055 0.14504 0.77094 0.11059 0.64949 0.09316 58216.304084 0.000761 0.35786 0.04976 0.98099 0 1.82804 0.13086 1.53632 0.10997 0.65418 0.07797 0.54922 0.06546
