/* ** ** Swift/XRT hardness ratio for Mrk 421. ** 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 56002.266709 0.000709 0.11846 0.00903 0.98367 0 17.35139 0.42636 13.84769 0.34021 2.05545 0.14839 1.63938 0.11831 56002.268153 0.000735 0.11596 0.00895 0.98819 0 17.11807 0.42085 13.44378 0.33054 1.98498 0.14523 1.55926 0.11408 56002.269606 0.000718 0.11619 0.00891 0.99194 0 17.39306 0.42746 13.75295 0.33801 2.02097 0.14687 1.59851 0.11616 56002.271171 0.000848 0.10195 0.00760 0.98976 0 17.25487 0.39357 13.55846 0.30924 1.75908 0.12492 1.38211 0.09815 56002.272644 0.000625 0.13706 0.01067 0.98611 0 17.04458 0.45483 13.41252 0.35788 2.33607 0.17094 1.83744 0.13443 56002.273929 0.000660 0.12899 0.00988 0.98246 0 17.43707 0.44871 13.66671 0.35168 2.24917 0.16227 1.76380 0.12729 56002.275723 0.001134 0.11548 0.00718 0.98214 0 17.11082 0.33979 13.32486 0.26459 1.97590 0.11635 1.53653 0.09049
