/* ** ** 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 56046.020167 0.001635 0.11844 0.02836 0.97168 0 0.89651 0.06925 0.62237 0.04803 0.10618 0.02406 0.07217 0.01633 56046.023831 0.002028 0.11671 0.02763 0.98288 0 0.72461 0.05638 0.49835 0.03877 0.08457 0.01891 0.05815 0.01300 56046.027416 0.001557 0.12816 0.03084 0.97212 0 0.85847 0.07032 0.59095 0.04840 0.11002 0.02489 0.07576 0.01714 56046.030489 0.001516 0.11580 0.02751 0.96947 0 0.99093 0.07582 0.67878 0.05193 0.11475 0.02581 0.07843 0.01764 56046.033721 0.001716 0.15639 0.03306 0.97911 0 0.83749 0.06599 0.57323 0.04517 0.13097 0.02569 0.08971 0.01759 56046.087973 0.001453 0.10589 0.02492 0.98008 0 1.03674 0.07611 0.77127 0.05661 0.10978 0.02455 0.08144 0.01821 56046.092293 0.002867 0.09671 0.01725 0.96905 0 1.00153 0.05342 0.74682 0.03983 0.09686 0.01649 0.07255 0.01235 56046.153842 0.002034 0.08717 0.02046 0.97724 0 0.88204 0.05916 0.66545 0.04463 0.07689 0.01730 0.05800 0.01305 56046.157581 0.001704 0.09484 0.02221 0.96944 0 0.99315 0.06905 0.74209 0.05158 0.09419 0.02106 0.07017 0.01569 56046.160402 0.001117 0.14543 0.03525 0.98446 0 0.95699 0.08288 0.71895 0.06226 0.13918 0.03150 0.10426 0.02359 56046.162803 0.001285 0.12509 0.02987 0.97748 0 0.98127 0.07861 0.73485 0.05886 0.12275 0.02761 0.09180 0.02065 56046.166079 0.001991 0.10415 0.02078 0.97033 0 1.06708 0.06582 0.80288 0.04952 0.11113 0.02109 0.08369 0.01588 56046.220273 0.001756 0.09675 0.02281 0.97694 0 0.92534 0.06522 0.69730 0.04914 0.08953 0.02014 0.06719 0.01511 56046.224509 0.002480 0.06510 0.01503 0.96616 0 0.99458 0.05719 0.74511 0.04283 0.06474 0.01448 0.04839 0.01082 56046.228612 0.001623 0.11596 0.02774 0.97861 0 0.83476 0.06477 0.62114 0.04819 0.09680 0.02191 0.07218 0.01633 56046.232475 0.002240 0.12661 0.02473 0.95220 0 0.86632 0.05659 0.64367 0.04204 0.10969 0.02019 0.08095 0.01489
