/* ** ** 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 60141.867484 0.000113 0.17101 0.05595 0.95097 0 4.08971 0.51960 3.47432 0.44141 0.69936 0.21087 0.59412 0.17914 60141.869020 0.001409 0.10862 0.02514 0.97938 1 3.28708 0.23740 0.81014 0.05851 0.35704 0.07851 0.08780 0.01931 60141.871838 0.001409 0.10436 0.02452 0.95876 1 3.36240 0.24279 0.82348 0.05946 0.35089 0.07847 0.08602 0.01924 60141.874089 0.000842 0.21610 0.05233 0.96552 1 2.81472 0.28558 0.69239 0.07025 0.60825 0.13375 0.14894 0.03275 60141.876035 0.001104 0.13538 0.03231 0.97368 1 3.22457 0.26888 0.79735 0.06649 0.43656 0.09762 0.10811 0.02417 60141.878752 0.001583 0.11416 0.02690 0.95413 1 2.73394 0.20352 0.67339 0.05013 0.31210 0.06979 0.07692 0.01720 60141.881381 0.001046 0.13315 0.03166 0.95833 1 3.51766 0.28460 0.86739 0.07018 0.46839 0.10474 0.11594 0.02593
