/* ** ** 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 59256.201855 0.000362 0.09485 0.01439 0.97600 0 9.56528 0.42148 8.47434 0.37337 0.90730 0.13167 0.80419 0.11672 59256.203252 0.001036 0.13164 0.00997 0.98324 0 9.72660 0.25137 8.57631 0.22164 1.28042 0.09113 1.13242 0.08059 59256.204899 0.000611 0.11456 0.01213 0.98104 0 9.83956 0.33103 8.57369 0.28845 1.12723 0.11317 0.98193 0.09860 59256.205816 0.000307 0.10638 0.01622 0.97170 0 10.30763 0.48168 8.95403 0.41842 1.09656 0.15916 0.95253 0.13825 59256.207225 0.001102 0.12531 0.00954 0.97375 0 9.75739 0.24598 8.51475 0.21464 1.22266 0.08788 1.06611 0.07662 59256.210058 0.001730 0.13893 0.00813 0.97492 0 9.71513 0.19633 8.45581 0.17088 1.34972 0.07416 1.17457 0.06453
