/* ** ** 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 56586.447517 0.000697 1.04777 0.34348 1.00000 1 0.19441 0.04638 0.15816 0.03773 0.20370 0.04580 0.16581 0.03728 56586.449477 0.001264 0.48944 0.13462 1.00000 1 0.23187 0.03713 0.18795 0.03010 0.11348 0.02538 0.09195 0.02056 56586.451685 0.000944 0.63197 0.18273 1.00000 1 0.24114 0.04347 0.19311 0.03480 0.15239 0.03445 0.12181 0.02754 56586.453733 0.001104 0.78211 0.21839 0.98294 1 0.19343 0.03592 0.15739 0.02923 0.15128 0.03155 0.12315 0.02568 56586.582111 0.001264 0.51677 0.14404 0.98851 1 0.23168 0.03780 0.17788 0.02902 0.11972 0.02706 0.09209 0.02081 56586.584275 0.000901 0.60365 0.17286 1.00000 1 0.27802 0.04931 0.21267 0.03772 0.16782 0.03773 0.12839 0.02886 56586.587020 0.001845 0.58184 0.12902 0.99253 1 0.23461 0.03205 0.17933 0.02450 0.13651 0.02384 0.10440 0.01823
