/* ** ** 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 55883.428137 0.000436 0.80590 0.23759 1.00000 1 0.42093 0.08290 0.34529 0.06800 0.33923 0.07442 0.27862 0.06112 55883.429255 0.000683 0.81413 0.24650 1.00000 1 0.25381 0.05181 0.20870 0.04260 0.20664 0.04621 0.17021 0.03806 55883.430403 0.000465 1.14551 0.37920 0.96875 1 0.27276 0.06658 0.22529 0.05499 0.31244 0.06986 0.25807 0.05771 55883.431492 0.000625 0.88334 0.26908 0.97674 1 0.27433 0.05831 0.22586 0.04800 0.24233 0.05288 0.20000 0.04364 55883.432800 0.000683 0.60853 0.17404 1.00000 1 0.33693 0.05956 0.27826 0.04919 0.20503 0.04610 0.16933 0.03807 55883.434368 0.000886 0.44301 0.12000 1.00000 1 0.35854 0.05482 0.29584 0.04523 0.15884 0.03552 0.13115 0.02933 55883.435952 0.000697 0.62892 0.18339 1.00000 1 0.31924 0.05928 0.26364 0.04896 0.20077 0.04514 0.16581 0.03728 55883.437128 0.000479 1.07813 0.35230 1.00000 1 0.27087 0.06423 0.22371 0.05305 0.29204 0.06566 0.24117 0.05422 55883.438581 0.000973 0.85708 0.21129 0.96484 1 0.27012 0.04543 0.22306 0.03752 0.23151 0.04173 0.19118 0.03446
