/* ** ** 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 56544.342687 0.001082 0.54921 0.15299 0.95187 0 0.28102 0.04667 0.20569 0.03415 0.15434 0.03452 0.11255 0.02517 56544.344521 0.000752 0.67880 0.19906 0.97308 0 0.32169 0.06050 0.23240 0.04371 0.21837 0.04913 0.15745 0.03542 56544.345959 0.000686 1.17311 0.38811 0.95781 0 0.20772 0.05039 0.15003 0.03639 0.24368 0.05482 0.17549 0.03948 56544.347571 0.000926 0.80182 0.24443 0.96562 0 0.22107 0.04513 0.16080 0.03282 0.17726 0.04013 0.12817 0.02901 56544.349544 0.001047 0.54865 0.15728 0.99171 0 0.27315 0.04702 0.19676 0.03387 0.14987 0.03435 0.10903 0.02499 56544.351570 0.000978 0.64590 0.16399 0.95562 0 0.34260 0.05484 0.24676 0.03950 0.22128 0.04361 0.16054 0.03163
