/* ** ** 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 59738.254815 0.000258 0.15143 0.01162 1.00000 0 32.66380 0.91268 29.62318 0.82769 4.94612 0.35346 4.48373 0.32042 59738.255299 0.000226 0.19085 0.01500 0.98718 0 29.79702 0.93541 27.18152 0.85330 5.68665 0.40960 5.18755 0.37365 59738.255733 0.000208 0.19983 0.01582 1.00000 0 30.41924 0.98132 27.77462 0.89601 6.07870 0.43955 5.55050 0.40135 59738.256152 0.000211 0.18948 0.01497 1.00000 0 31.32492 0.98943 28.58800 0.90298 5.93546 0.42976 5.41691 0.39221 59738.256560 0.000197 0.20427 0.01600 1.00000 0 31.46489 1.02797 28.71519 0.93813 6.42726 0.45746 5.86554 0.41748 59738.257185 0.000428 0.17653 0.00993 0.99010 0 32.75523 0.71039 29.88545 0.64815 5.78218 0.30019 5.27546 0.27388
