/* ** ** 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 56212.525013 0.001249 0.70553 0.20854 1.00000 1 0.19401 0.03715 0.13036 0.02491 0.13688 0.03082 0.09256 0.02081 56212.526988 0.000726 1.08232 0.35252 0.98000 1 0.21678 0.05110 0.15000 0.03536 0.23462 0.05274 0.16246 0.03652 56212.528339 0.000625 1.38580 0.48395 0.93023 1 0.20687 0.05529 0.14359 0.03838 0.28668 0.06444 0.19901 0.04473 56212.529400 0.000436 1.75943 0.66578 1.00000 1 0.21695 0.06604 0.15035 0.04577 0.38171 0.08580 0.26534 0.05964 56212.530634 0.000799 0.65512 0.18541 1.00000 1 0.33677 0.06069 0.23321 0.04203 0.22062 0.04814 0.15273 0.03333 56212.533423 0.001990 0.73425 0.15739 0.97187 1 0.22921 0.03255 0.15936 0.02263 0.16830 0.02702 0.11687 0.01876
