/* ** ** 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 55743.425294 0.001583 0.44563 0.11985 0.98165 1 0.20848 0.03115 0.16786 0.02508 0.09291 0.02077 0.07477 0.01672 55743.428286 0.001409 0.67180 0.19587 0.97938 1 0.15476 0.02874 0.12473 0.02316 0.10397 0.02337 0.08379 0.01883 55743.430959 0.001264 0.58473 0.16515 0.97701 1 0.19970 0.03446 0.16096 0.02777 0.11677 0.02611 0.09412 0.02105 55743.433675 0.001453 0.48782 0.13305 0.97000 1 0.20966 0.03274 0.16907 0.02640 0.10228 0.02287 0.08247 0.01844 55743.435796 0.000668 0.98553 0.32099 1.00000 1 0.21781 0.05134 0.17561 0.04139 0.21465 0.04825 0.17305 0.03890 55743.437132 0.000668 1.08966 0.35491 1.00000 1 0.19903 0.04691 0.16000 0.03771 0.21687 0.04875 0.17305 0.03890 55743.438599 0.000799 1.00967 0.32603 1.00000 1 0.17694 0.04082 0.14265 0.03291 0.17865 0.04037 0.14401 0.03254 55743.440313 0.000915 0.63918 0.18265 0.96825 1 0.25442 0.04527 0.20517 0.03651 0.16262 0.03636 0.13115 0.02933 55743.442840 0.001612 0.57141 0.14967 0.97506 1 0.18465 0.02927 0.14884 0.02360 0.10551 0.02200 0.08500 0.01772
