/* ** ** 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 55918.281476 0.000523 0.76679 0.23072 1.00000 1 0.35031 0.06956 0.28550 0.05669 0.26862 0.06072 0.21997 0.04972 55918.282449 0.000450 1.38221 0.48169 1.00000 1 0.22906 0.06122 0.18667 0.04989 0.31661 0.07080 0.25807 0.05771 55918.283423 0.000523 0.75905 0.22861 1.00000 1 0.35686 0.07199 0.29173 0.05885 0.27087 0.06057 0.22222 0.04969 55918.284396 0.000450 1.08899 0.35280 0.93548 1 0.30697 0.07124 0.25063 0.05815 0.33429 0.07557 0.27306 0.06172 55918.285340 0.000494 0.82792 0.25140 0.97059 1 0.35602 0.07268 0.29091 0.05938 0.29476 0.06626 0.24119 0.05422 55918.286284 0.000450 1.25587 0.43354 1.00000 1 0.25242 0.06612 0.20410 0.05346 0.31700 0.07127 0.25676 0.05772 55918.287170 0.000436 1.21413 0.39752 0.96667 1 0.29229 0.07134 0.24141 0.05892 0.35488 0.07745 0.28966 0.06321 55918.288056 0.000421 1.03371 0.32777 0.96552 1 0.33280 0.07442 0.27586 0.06169 0.34402 0.07734 0.28427 0.06390 55918.288942 0.000465 1.23409 0.40265 0.96875 1 0.26796 0.06499 0.21936 0.05320 0.33068 0.07216 0.27097 0.05913 55918.290046 0.000639 0.59858 0.17027 1.00000 1 0.37093 0.06521 0.30414 0.05346 0.22203 0.04965 0.18182 0.04066 55918.291499 0.000813 1.00757 0.25243 0.98057 1 0.28922 0.05195 0.23846 0.04283 0.29141 0.05090 0.23965 0.04185
