/* ** ** Swift/XRT hardness ratio for BL Lacertae. ** 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 55146.676315 0.000596 0.95169 0.30256 1.00000 1 0.24820 0.05580 0.20410 0.04588 0.23621 0.05310 0.19414 0.04364 55146.677797 0.000886 0.57631 0.16089 0.95082 1 0.29029 0.04852 0.23933 0.04001 0.16730 0.03741 0.13793 0.03084 55146.679264 0.000581 0.88931 0.27196 1.00000 1 0.28773 0.06164 0.23675 0.05072 0.25588 0.05584 0.21000 0.04583 55146.681109 0.001264 0.35843 0.09346 0.97701 1 0.31851 0.04272 0.26258 0.03522 0.11416 0.02553 0.09412 0.02105 55146.682953 0.000581 0.71413 0.20649 0.97500 1 0.36580 0.06939 0.30162 0.05722 0.26123 0.05701 0.21539 0.04700 55146.684304 0.000770 0.77531 0.23461 1.00000 1 0.23496 0.04760 0.19371 0.03924 0.18217 0.04095 0.15018 0.03376 55146.685917 0.000842 0.69668 0.17995 0.98192 1 0.31664 0.05293 0.26109 0.04364 0.22060 0.04344 0.18191 0.03582
