/* ** ** 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 57681.194653 0.001759 0.08542 0.01994 0.98026 0 1.04890 0.07013 0.78327 0.05236 0.08959 0.02004 0.06723 0.01503 57681.197697 0.001285 0.14151 0.03408 0.98198 0 0.85945 0.07396 0.64503 0.05550 0.12162 0.02736 0.09138 0.02056 57681.200040 0.001059 0.13694 0.03270 0.98361 0 1.07047 0.08972 0.81278 0.06812 0.14659 0.03278 0.11130 0.02489 57681.202477 0.001377 0.10315 0.02428 0.98950 0 1.08679 0.08004 0.82273 0.06059 0.11210 0.02507 0.08507 0.01902 57681.205061 0.001207 0.11507 0.02658 0.98804 0 1.17418 0.08899 0.88806 0.06730 0.13511 0.02948 0.10211 0.02228 57681.251366 0.002442 0.07716 0.01808 0.96682 0 1.19878 0.07770 0.61563 0.03939 0.09250 0.02083 0.04910 0.01098 57681.256771 0.002963 0.10795 0.02046 0.96387 0 1.06396 0.06394 0.58013 0.03483 0.11485 0.02065 0.06292 0.01130
