/* ** ** 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 59336.254731 0.000587 0.15298 0.01166 0.99507 0 14.78638 0.41347 13.05113 0.36438 2.26196 0.16037 1.99444 0.14123 59336.255932 0.000613 0.13700 0.01054 1.00000 0 15.46788 0.41376 13.58726 0.36341 2.11906 0.15285 1.86452 0.13444 59336.257106 0.000561 0.15472 0.01184 0.98969 0 15.09681 0.42364 13.42596 0.37673 2.33575 0.16624 2.07745 0.14786 59336.258272 0.000605 0.14796 0.01142 0.98565 0 14.66815 0.40374 12.97020 0.35699 2.17034 0.15648 1.91883 0.13836 59336.259476 0.000599 0.14781 0.01132 0.99517 0 14.80090 0.40887 13.10217 0.36188 2.18773 0.15634 1.93727 0.13842 59336.260929 0.000854 0.13222 0.00902 0.98018 0 15.50601 0.35204 13.59260 0.30861 2.05017 0.13187 1.79538 0.11548
