/* ** ** 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 55966.374240 0.000310 0.37731 0.06324 0.98131 0 2.94684 0.26108 2.51672 0.22298 1.11188 0.15820 0.94887 0.13501 55966.375588 0.001039 0.42316 0.03594 0.95543 0 3.25234 0.15037 2.74468 0.12690 1.37625 0.09807 1.16032 0.08267 55966.377015 0.000388 0.38949 0.05727 0.97761 0 3.02856 0.23636 2.54574 0.19868 1.17959 0.14700 0.98993 0.12336 55966.377724 0.000321 0.36159 0.06008 0.98198 0 3.01968 0.25898 2.53014 0.21697 1.09188 0.15537 0.91405 0.13005 55966.378343 0.000298 0.41171 0.06936 0.98058 0 2.88045 0.26363 2.40788 0.22036 1.18591 0.16772 0.99175 0.14025 55966.378968 0.000327 0.31896 0.05208 1.00000 0 3.31463 0.27050 2.78392 0.22716 1.05725 0.14953 0.88643 0.12536 55966.379602 0.000307 0.34033 0.05583 0.99057 0 3.31627 0.27560 2.80207 0.23287 1.12864 0.15962 0.95397 0.13491 55966.380215 0.000307 0.39432 0.06649 0.97170 0 2.93640 0.26564 2.45233 0.22184 1.15788 0.16476 0.96729 0.13763 55966.380878 0.000356 0.29599 0.04783 0.95122 0 3.40636 0.26083 2.87409 0.22005 1.00824 0.14347 0.85155 0.12116 55966.381575 0.000341 0.29156 0.04423 0.95763 0 4.08106 0.29302 3.40851 0.24473 1.18987 0.15901 0.99280 0.13267 55966.382281 0.000365 0.29888 0.04768 0.94444 0 3.52440 0.26582 2.92500 0.22061 1.05339 0.14807 0.87423 0.12289 55966.383719 0.001073 0.40725 0.03458 0.97574 0 3.21719 0.14646 2.68524 0.12224 1.31019 0.09392 1.09350 0.07839 55966.385085 0.000292 0.32145 0.05290 1.00000 0 3.65905 0.29701 3.05439 0.24791 1.17619 0.16840 0.98114 0.14046 55966.386416 0.001039 0.41899 0.03637 0.97772 0 3.08841 0.14619 2.59718 0.12292 1.29400 0.09414 1.08821 0.07916
