/* ** ** 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 55153.431458 0.035204 0.25454 0.04689 0.13401 1 0.21873 0.01817 0.17865 0.01484 0.05568 0.00915 0.04557 0.00749 55153.469436 0.002774 0.28918 0.07014 0.99820 1 0.19405 0.02244 0.15966 0.01846 0.05612 0.01196 0.04616 0.00984 55153.633879 0.104289 0.37611 0.07888 0.06073 1 0.17740 0.01915 0.09607 0.00949 0.06672 0.01200 0.03378 0.00558 55153.739621 0.001453 0.40491 0.10784 1.00000 1 0.24161 0.03495 0.19752 0.02857 0.09783 0.02188 0.08000 0.01789 55153.744487 0.003413 0.19389 0.04624 0.98920 1 0.22886 0.02202 0.18664 0.01796 0.04437 0.00968 0.03614 0.00789 55153.801946 0.001932 0.33582 0.08689 0.99248 1 0.21889 0.02850 0.18015 0.02345 0.07351 0.01644 0.06061 0.01355 55153.805519 0.001641 0.46613 0.12627 0.99115 1 0.18637 0.02849 0.15321 0.02342 0.08687 0.01943 0.07143 0.01597 55153.809179 0.002019 0.30918 0.07954 1.00000 1 0.22559 0.02870 0.18616 0.02368 0.06975 0.01560 0.05755 0.01287 55153.812883 0.001685 0.41573 0.10573 0.98673 1 0.22407 0.03107 0.18495 0.02565 0.09315 0.01986 0.07688 0.01639 55153.870414 0.003123 0.38884 0.07549 0.97674 1 0.22043 0.02260 0.18038 0.01849 0.08571 0.01413 0.07029 0.01159
