/* ** ** 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 53953.150669 0.000561 0.10060 0.01524 0.94845 0 5.92415 0.26502 5.29926 0.23704 0.59596 0.08625 0.53421 0.07732 53953.151772 0.000541 0.10323 0.01519 0.98396 0 6.05058 0.27256 5.36660 0.24174 0.62462 0.08747 0.55527 0.07775 53953.152923 0.000611 0.10929 0.01464 0.96706 0 6.30415 0.26256 5.66898 0.23610 0.68900 0.08769 0.61918 0.07881 53953.154661 0.001118 0.07437 0.01726 1.00000 1 5.53918 0.34396 1.39924 0.08688 0.41196 0.09212 0.10390 0.02323 53953.156433 0.000654 0.15705 0.03780 0.97778 1 4.53993 0.40428 1.15563 0.10290 0.71298 0.15943 0.18182 0.04066 53953.159092 0.002005 0.08076 0.01474 0.93581 1 4.91982 0.24216 1.25300 0.06167 0.39734 0.06984 0.10130 0.01780
