/* ** ** 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 55747.373276 0.000654 1.02760 0.32671 0.95556 1 0.21898 0.04924 0.18091 0.04067 0.22503 0.05059 0.18511 0.04161 55747.375063 0.001133 0.77808 0.23267 0.97436 1 0.16635 0.03303 0.13526 0.02685 0.12944 0.02894 0.10526 0.02354 55747.377634 0.001438 0.43524 0.11706 0.98990 1 0.23002 0.03437 0.18708 0.02795 0.10011 0.02239 0.08163 0.01825 55747.379944 0.000872 0.80532 0.23995 0.95000 1 0.21532 0.04240 0.17559 0.03458 0.17340 0.03877 0.14035 0.03138 55747.381832 0.001017 0.82947 0.25217 0.98571 1 0.17155 0.03533 0.14000 0.02883 0.14230 0.03182 0.11594 0.02593 55747.383735 0.000886 0.78472 0.23341 0.95082 1 0.21605 0.04238 0.17627 0.03457 0.16954 0.03791 0.13793 0.03084 55747.385550 0.000930 0.66010 0.19310 1.00000 1 0.22720 0.04219 0.18710 0.03474 0.14997 0.03390 0.12375 0.02797 55747.387352 0.000842 0.77039 0.22368 0.92109 1 0.24904 0.04707 0.20208 0.03819 0.19186 0.04229 0.15573 0.03433 55747.442865 0.003646 0.49941 0.12287 0.97295 1 0.22196 0.03153 0.08131 0.01155 0.11085 0.02227 0.04079 0.00819
