/* ** ** 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 57640.764681 0.000547 0.12705 0.03020 0.98942 0 1.95152 0.15742 1.68693 0.13608 0.24794 0.05544 0.21426 0.04791 57640.765827 0.000599 0.12051 0.02895 0.97585 0 1.89493 0.14887 1.62329 0.12753 0.22836 0.05183 0.19573 0.04443 57640.767155 0.000729 0.09884 0.02318 0.97222 0 1.93447 0.13677 1.65608 0.11708 0.19119 0.04276 0.16354 0.03657 57640.768769 0.000885 0.07744 0.01781 0.98366 0 2.06441 0.12843 1.78241 0.11089 0.15986 0.03539 0.13801 0.03055 57640.770132 0.000477 0.14418 0.03459 0.99394 0 1.98670 0.17276 1.69953 0.14777 0.28645 0.06406 0.24431 0.05463 57640.771429 0.000819 0.08523 0.01988 0.98233 0 1.96686 0.13036 1.68616 0.11174 0.16763 0.03749 0.14412 0.03223 57640.773972 0.001725 0.07189 0.01277 0.97651 0 1.90227 0.08834 1.62633 0.07552 0.13676 0.02346 0.11703 0.02007
