/* ** ** 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 56861.804126 0.000642 0.12344 0.01861 0.98198 0 4.29260 0.21441 3.70312 0.18496 0.52990 0.07539 0.45704 0.06503 56861.805454 0.000686 0.11211 0.01682 0.97468 0 4.56326 0.21660 3.86036 0.18321 0.51160 0.07280 0.43132 0.06137 56861.806452 0.000312 0.11836 0.02774 0.98148 0 3.93873 0.30280 3.31085 0.25450 0.46618 0.10321 0.39187 0.08675 56861.807337 0.000573 0.14285 0.02161 0.97980 0 4.28426 0.22981 3.61922 0.19411 0.61201 0.08656 0.51632 0.07302 56861.808547 0.000637 0.12610 0.01909 0.97727 0 4.37167 0.22251 3.69342 0.18797 0.55126 0.07859 0.46779 0.06668 56861.810159 0.000975 0.09995 0.01350 0.98080 0 4.42684 0.17938 3.70928 0.15030 0.44248 0.05703 0.37096 0.04781 56861.868384 0.000295 0.10087 0.02404 0.99020 0 4.48903 0.32670 3.86828 0.28147 0.45281 0.10277 0.39149 0.08886 56861.869272 0.000593 0.15260 0.02316 0.97073 0 3.85258 0.21217 3.29931 0.18169 0.58790 0.08315 0.50335 0.07118 56861.870467 0.000602 0.12677 0.01926 0.98558 0 4.40549 0.22485 3.80877 0.19439 0.55849 0.07993 0.48348 0.06920 56861.871630 0.000561 0.09902 0.01733 0.95876 0 4.56479 0.23740 3.96769 0.20634 0.45202 0.07552 0.39285 0.06564 56861.872802 0.000611 0.12359 0.01866 0.98104 0 4.49737 0.22722 3.88949 0.19650 0.55584 0.07908 0.48135 0.06848 56861.874040 0.000628 0.12132 0.01826 0.97235 0 4.48336 0.21999 3.89152 0.19095 0.54390 0.07738 0.47223 0.06718 56861.875302 0.000634 0.14411 0.02180 0.96347 0 3.79328 0.20335 3.29417 0.17659 0.54665 0.07731 0.47472 0.06714 56861.876488 0.000553 0.14165 0.02142 0.98429 0 4.32775 0.23169 3.75996 0.20129 0.61305 0.08670 0.53280 0.07535 56861.877394 0.000353 0.10964 0.02313 0.98361 0 4.37129 0.29347 3.80568 0.25550 0.47928 0.09586 0.41736 0.08347
