/* ** ** Swift/XRT hardness ratio for PKS 2155-304. ** 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 56815.533762 0.000799 0.08940 0.02088 0.96377 0 2.05230 0.13773 1.68115 0.11275 0.18348 0.04104 0.15063 0.03368 56815.535591 0.001030 0.08705 0.02031 0.96910 0 1.60141 0.10654 1.33463 0.08879 0.13940 0.03117 0.11614 0.02597 56815.537098 0.000477 0.20182 0.04953 0.97576 0 1.48032 0.14968 1.23297 0.12467 0.29875 0.06680 0.24886 0.05565 56815.538201 0.000625 0.11046 0.02609 0.98611 0 2.04405 0.15528 1.70229 0.12932 0.22579 0.05049 0.18811 0.04206 56815.539893 0.001068 0.08723 0.02035 0.97019 0 1.53858 0.10251 1.28244 0.08545 0.13422 0.03001 0.11192 0.02503 56815.542608 0.001646 0.09511 0.01594 0.97891 0 1.77405 0.08802 1.47670 0.07326 0.16873 0.02702 0.14027 0.02246
