/* ** ** 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 56541.278802 0.000642 0.88657 0.27724 0.81532 0 0.38689 0.08189 0.24291 0.05142 0.34300 0.07895 0.21536 0.04957 56541.280110 0.000666 0.88066 0.27510 0.86087 0 0.36200 0.07799 0.22728 0.04897 0.31880 0.07211 0.20016 0.04528 56541.282063 0.001288 0.51439 0.11824 0.93186 0 0.44063 0.05944 0.27666 0.03732 0.22666 0.04219 0.14231 0.02649 56541.601963 0.000911 1.29971 0.44502 0.95556 0 0.24116 0.06227 0.10186 0.02630 0.31344 0.07049 0.13239 0.02977 56541.605227 0.002352 0.50053 0.13845 0.96925 0 0.23920 0.03853 0.10104 0.01627 0.11973 0.02692 0.05057 0.01137 56541.610041 0.002462 0.77740 0.18870 0.96005 0 0.22908 0.03690 0.09676 0.01558 0.17808 0.03234 0.07522 0.01366
