/* ** ** Swift/XRT hardness ratio for OJ 287. ** 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 55880.118817 0.001423 0.42397 0.11364 1.00000 1 0.23859 0.03526 0.19327 0.02856 0.10115 0.02262 0.08163 0.01825 55880.122158 0.001917 0.32877 0.08493 0.99242 1 0.22861 0.02956 0.18574 0.02402 0.07516 0.01681 0.06107 0.01366 55880.126297 0.002222 0.31674 0.08148 0.99346 1 0.20449 0.02601 0.16618 0.02114 0.06477 0.01448 0.05263 0.01177 55880.130176 0.001656 0.35054 0.09155 0.98246 1 0.25005 0.03324 0.20286 0.02697 0.08765 0.01970 0.07107 0.01598 55880.133967 0.002135 0.40336 0.08208 0.98168 1 0.28774 0.03151 0.23363 0.02559 0.11606 0.01990 0.09424 0.01616 55880.722583 0.001365 0.47694 0.12969 0.97872 1 0.22682 0.03509 0.18217 0.02818 0.10818 0.02419 0.08696 0.01944 55880.725546 0.001598 0.36360 0.09523 0.96364 1 0.25518 0.03429 0.20629 0.02772 0.09278 0.02086 0.07509 0.01688 55880.728698 0.001554 0.41056 0.10924 0.96262 1 0.23427 0.03334 0.18754 0.02669 0.09618 0.02162 0.07728 0.01737 55880.732765 0.002513 0.25195 0.06309 0.98844 1 0.22986 0.02590 0.18565 0.02092 0.05791 0.01295 0.04678 0.01046 55880.737777 0.002469 0.33831 0.07426 0.97484 1 0.24896 0.02749 0.20000 0.02209 0.08423 0.01598 0.06734 0.01277
