/* ** ** 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 56819.070375 0.000567 0.11488 0.02718 0.97959 0 2.11677 0.16361 1.81484 0.14026 0.24318 0.05438 0.20868 0.04666 56819.071729 0.000787 0.08327 0.01939 0.95956 0 2.14735 0.13936 1.84334 0.11963 0.17882 0.03998 0.15351 0.03433 56819.073222 0.000706 0.10624 0.02502 0.97541 0 1.86363 0.13775 1.58853 0.11742 0.19799 0.04428 0.16835 0.03764 56819.074446 0.000518 0.14123 0.03379 0.98324 0 1.89060 0.16069 1.61654 0.13740 0.26701 0.05971 0.22765 0.05090 56819.075496 0.000532 0.11934 0.02827 0.98913 0 2.14969 0.16807 1.84594 0.14432 0.25654 0.05737 0.22015 0.04923 56819.076671 0.000642 0.11503 0.02757 0.97748 0 1.85713 0.14302 1.58427 0.12200 0.21362 0.04849 0.18218 0.04136 56819.078043 0.000729 0.09281 0.02171 0.98016 0 2.03991 0.14004 1.74277 0.11963 0.18933 0.04234 0.16221 0.03627 56819.080010 0.001238 0.09313 0.01647 0.98364 0 2.09988 0.10940 1.79124 0.09332 0.19556 0.03306 0.16655 0.02815
