/* ** ** 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 56623.213230 0.001031 0.73021 0.21787 1.00000 1 0.18731 0.03674 0.15294 0.02999 0.13678 0.03075 0.11211 0.02520 56623.215118 0.000857 1.01324 0.31825 0.94915 1 0.18149 0.04080 0.14740 0.03314 0.18389 0.04034 0.14928 0.03274 56623.216658 0.000683 1.08304 0.35190 0.97467 1 0.19758 0.04657 0.16068 0.03787 0.21399 0.04785 0.17464 0.03905 56623.287360 0.001060 0.70285 0.20430 0.97260 1 0.19549 0.03630 0.16111 0.02992 0.13740 0.03073 0.11268 0.02520 56623.289103 0.000683 0.97930 0.31140 1.00000 1 0.21063 0.04736 0.17301 0.03890 0.20627 0.04638 0.16933 0.03807 56623.291064 0.001278 0.64116 0.15268 0.96912 1 0.25835 0.03851 0.21176 0.03157 0.16564 0.03076 0.13602 0.02526
