/* ** ** 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 55955.404547 0.000376 0.09217 0.01380 1.00000 0 9.72781 0.42345 8.25638 0.35934 0.89665 0.12847 0.76246 0.10926 55955.405502 0.000579 0.10997 0.01187 0.99500 0 10.38106 0.35152 8.93010 0.30238 1.14156 0.11705 0.98084 0.10058 55955.406463 0.000382 0.11334 0.01513 0.99242 0 9.96631 0.42281 8.62885 0.36607 1.12961 0.14300 0.97803 0.12381 55955.407151 0.000307 0.10590 0.01604 0.99057 0 10.49728 0.48902 9.08590 0.42327 1.11163 0.16020 0.96220 0.13866 55955.407791 0.000333 0.09978 0.01500 0.98261 0 10.19273 0.46167 8.77175 0.39728 1.01707 0.14575 0.87716 0.12570 55955.408445 0.000321 0.11214 0.01611 0.98198 0 10.25205 0.47160 8.84497 0.40684 1.14971 0.15646 0.99248 0.13506 55955.409159 0.000394 0.08226 0.01242 0.97059 0 10.47097 0.43172 9.01599 0.37172 0.86139 0.12508 0.74297 0.10790 55955.409949 0.000396 0.11202 0.01499 0.98540 0 9.93128 0.41498 8.59784 0.35926 1.11252 0.14144 0.96321 0.12245 55955.410696 0.000350 0.10102 0.01499 0.96694 0 9.90008 0.44349 8.47621 0.37970 1.00014 0.14145 0.85613 0.12107 55955.411405 0.000359 0.09117 0.01347 0.96774 0 10.57459 0.45071 9.15601 0.39025 0.96406 0.13634 0.83472 0.11805 55955.412091 0.000327 0.10254 0.01583 0.99115 0 9.75680 0.45312 8.44707 0.39229 1.00049 0.14727 0.86629 0.12751 55955.412730 0.000312 0.10365 0.01560 0.98148 0 10.41867 0.47777 9.02095 0.41368 1.07992 0.15476 0.93509 0.13400 55955.413352 0.000310 0.11664 0.01727 0.98131 0 9.66034 0.46460 8.34835 0.40149 1.12682 0.15779 0.97305 0.13625 55955.414009 0.000347 0.13014 0.01851 0.95833 0 8.74248 0.41708 7.55418 0.36039 1.13778 0.15246 0.98385 0.13184 55955.414666 0.000310 0.11098 0.01659 0.99065 0 9.92495 0.46863 8.59577 0.40587 1.10143 0.15625 0.95399 0.13533 55955.415470 0.000495 0.10424 0.01291 0.97076 0 9.62181 0.36718 8.33364 0.31802 1.00296 0.11820 0.86892 0.10240
