/* ** ** 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 55701.162587 0.000538 0.12757 0.03026 0.94624 0 2.06085 0.16303 1.78459 0.14118 0.26290 0.05879 0.22765 0.05090 55701.163423 0.000298 0.21928 0.05505 0.98058 0 2.05949 0.22056 1.78473 0.19113 0.45160 0.10253 0.39139 0.08886 55701.164068 0.000347 0.23972 0.05584 0.96667 0 1.91375 0.19867 1.65700 0.17202 0.45877 0.09566 0.39721 0.08282 55701.165058 0.000642 0.10442 0.02492 0.97297 0 2.02216 0.14891 1.75228 0.12904 0.21116 0.04794 0.18301 0.04155 55701.166241 0.000541 0.13596 0.03294 0.97326 0 1.84792 0.15641 1.59508 0.13501 0.25124 0.05704 0.21720 0.04931 55701.167248 0.000466 0.15277 0.03727 0.98758 0 1.90317 0.17012 1.62061 0.14484 0.29075 0.06601 0.24862 0.05645 55701.168243 0.000530 0.11119 0.02662 0.98907 0 2.26787 0.17231 1.96483 0.14929 0.25215 0.05725 0.21840 0.04959 55701.169600 0.000828 0.08139 0.01894 0.97203 0 2.07713 0.13352 1.77984 0.11441 0.16906 0.03781 0.14412 0.03223 55701.171033 0.000605 0.10694 0.02518 0.97608 0 2.15525 0.15881 1.83501 0.13521 0.23049 0.05154 0.19641 0.04392 55701.172361 0.000723 0.07784 0.01862 1.00000 0 2.34924 0.14998 2.00654 0.12809 0.18286 0.04216 0.15598 0.03596 55701.173703 0.000619 0.09736 0.02286 0.99065 0 2.28679 0.16353 1.94745 0.13924 0.22265 0.04979 0.18899 0.04226 55701.175011 0.000689 0.11077 0.02488 0.95378 0 2.06652 0.14585 1.75401 0.12379 0.22891 0.04881 0.19416 0.04139
