/* ** ** 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 57434.096197 0.000822 0.08190 0.00748 0.98944 0 17.50219 0.43294 11.86515 0.29340 1.43336 0.12608 0.97175 0.08538 57434.097334 0.000315 0.07791 0.01162 0.95413 0 18.41190 0.72248 12.36796 0.48532 1.43444 0.20643 0.96460 0.13871 57434.097947 0.000298 0.08833 0.01293 1.00000 0 16.79417 0.71304 11.20851 0.47572 1.48344 0.20776 0.99194 0.13890 57434.098561 0.000315 0.08362 0.01233 0.99083 0 16.64778 0.69332 11.11083 0.46266 1.39203 0.19687 0.92747 0.13116 57434.099240 0.000365 0.06348 0.00977 0.99206 0 18.32200 0.67896 12.13684 0.44975 1.16312 0.17371 0.77171 0.11524 57434.099935 0.000330 0.07412 0.01207 0.95614 0 17.36435 0.69506 11.48925 0.45990 1.28706 0.20318 0.85103 0.13433 57434.100777 0.000512 0.09590 0.01037 0.98305 0 16.91129 0.54690 11.27464 0.36461 1.62187 0.16729 1.08226 0.11163
