/* ** ** 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 55710.332419 0.000799 0.69291 0.20508 1.00000 1 0.25338 0.04807 0.20667 0.03920 0.17557 0.03989 0.14327 0.03255 55710.334162 0.000944 0.39886 0.10610 0.98462 1 0.38507 0.05549 0.31355 0.04518 0.15359 0.03434 0.12500 0.02795 55710.335600 0.000494 0.72095 0.21305 0.97059 1 0.41172 0.07954 0.33625 0.06496 0.29683 0.06637 0.24243 0.05421 55710.336762 0.000668 0.59751 0.16721 0.97826 1 0.38258 0.06703 0.31238 0.05473 0.22860 0.04988 0.18667 0.04073 55710.337793 0.000363 1.10127 0.34501 0.92000 1 0.40626 0.09132 0.33167 0.07455 0.44740 0.09763 0.36522 0.07970 55710.338650 0.000494 0.82648 0.24864 1.00000 1 0.36435 0.07503 0.29750 0.06126 0.30113 0.06604 0.24588 0.05393 55710.339623 0.000479 0.59081 0.16884 1.00000 1 0.50251 0.08942 0.41033 0.07302 0.29689 0.06639 0.24243 0.05421 55710.340698 0.000596 0.63763 0.18387 1.00000 1 0.37478 0.06824 0.30600 0.05571 0.23897 0.05344 0.19512 0.04363 55710.341715 0.000421 0.82897 0.26028 1.00000 1 0.40759 0.08984 0.33280 0.07336 0.33788 0.07555 0.27586 0.06169 55710.342935 0.000799 0.65745 0.15291 0.98160 1 0.43903 0.06575 0.35840 0.05368 0.28864 0.05136 0.23561 0.04193
