/* ** ** 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 55506.448218 0.000857 0.97495 0.30702 0.98305 1 0.17312 0.03817 0.14099 0.03108 0.16878 0.03795 0.13723 0.03085 55506.449729 0.000654 1.10553 0.36010 0.97778 1 0.19980 0.04709 0.16364 0.03857 0.22088 0.04966 0.18089 0.04067 55506.451065 0.000683 1.16852 0.39193 0.97872 1 0.18173 0.04543 0.14884 0.03721 0.21236 0.04748 0.17391 0.03889 55506.452372 0.000625 0.86456 0.26644 0.95349 1 0.27279 0.05715 0.22340 0.04680 0.23584 0.05331 0.19313 0.04365 55506.453607 0.000610 0.88698 0.26843 1.00000 1 0.27398 0.05713 0.22439 0.04679 0.24302 0.05330 0.19903 0.04365 55506.454958 0.000741 0.71320 0.21076 0.96078 1 0.27953 0.05401 0.22892 0.04423 0.19936 0.04458 0.16327 0.03651 55506.456599 0.000901 0.67230 0.19715 1.00000 1 0.23544 0.04467 0.19240 0.03650 0.15829 0.03540 0.12903 0.02885 55506.458517 0.001017 0.83032 0.22081 0.95070 1 0.22980 0.04127 0.18788 0.03374 0.19081 0.03742 0.15628 0.03065
