/* ** ** 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 57183.722823 0.000735 0.10000 0.02381 0.96850 0 2.04741 0.14640 1.60483 0.11470 0.20475 0.04650 0.16076 0.03648 57183.724128 0.000570 0.12161 0.02886 0.98477 0 2.13955 0.17025 1.69792 0.13511 0.26019 0.05818 0.20653 0.04618 57183.725331 0.000634 0.10200 0.02431 0.97260 0 2.29228 0.16654 1.82117 0.13230 0.23382 0.05308 0.18567 0.04213 57183.726477 0.000512 0.12910 0.03079 0.98870 0 2.23749 0.18531 1.77281 0.14682 0.28887 0.06459 0.22895 0.05120 57183.727739 0.000749 0.12374 0.02438 0.97644 0 2.34398 0.15427 1.84719 0.12156 0.29005 0.05386 0.22972 0.04266 57183.989289 0.000524 0.11085 0.02652 0.98343 0 2.62510 0.19873 2.00299 0.15155 0.29099 0.06603 0.22220 0.05042 57183.990282 0.000469 0.12870 0.03111 0.98148 0 2.43673 0.20318 1.93324 0.16120 0.31360 0.07115 0.24875 0.05644 57183.991352 0.000602 0.10031 0.02356 0.97596 0 2.49199 0.17913 1.96021 0.14091 0.24996 0.05590 0.19737 0.04413 57183.992469 0.000515 0.11827 0.02805 0.97753 0 2.46937 0.19526 1.94874 0.15407 0.29205 0.06531 0.23027 0.05149 57183.993705 0.000720 0.14338 0.02495 0.97992 0 2.75909 0.17359 2.16535 0.13623 0.39561 0.06418 0.31199 0.05061
