/* ** ** 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 56817.869621 0.000900 0.09814 0.02301 0.98071 0 1.56110 0.10985 1.34209 0.09444 0.15321 0.03426 0.13137 0.02937 56817.871423 0.000903 0.10456 0.02573 0.99359 0 1.37243 0.10388 1.18193 0.08945 0.14350 0.03360 0.12404 0.02906 56817.873154 0.000828 0.10686 0.02554 0.97552 0 1.53920 0.11494 1.32140 0.09866 0.16447 0.03735 0.14168 0.03217 56817.874933 0.000952 0.08588 0.02033 0.97872 0 1.66701 0.11115 1.42490 0.09500 0.14316 0.03251 0.12276 0.02787 56817.876785 0.000900 0.09486 0.02254 0.97428 0 1.59256 0.11135 1.37248 0.09596 0.15106 0.03431 0.13046 0.02962 56817.878675 0.000990 0.11619 0.02412 0.98830 0 1.53031 0.10409 1.32458 0.09009 0.17780 0.03487 0.15410 0.03022
