/* ** ** 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 57031.041110 0.000414 0.25087 0.00895 1.00000 0 60.01168 0.95954 55.73460 0.89114 15.05530 0.48031 13.97163 0.44575 57031.041923 0.000399 0.25982 0.00935 1.00000 0 59.82771 0.97955 55.42416 0.90739 15.54432 0.49792 14.39131 0.46097 57031.042696 0.000373 0.28025 0.01011 1.00000 0 59.74678 1.00985 55.40174 0.93637 16.74398 0.53366 15.51899 0.49461 57031.043440 0.000370 0.28590 0.01041 1.00000 0 58.31459 1.00289 54.15441 0.93133 16.67231 0.53517 15.48494 0.49696 57031.044186 0.000376 0.27444 0.00994 1.00000 0 60.67754 1.02137 55.64486 0.93666 16.65218 0.53418 15.26212 0.48956 57031.044941 0.000379 0.26718 0.00968 1.00000 0 60.98030 1.01519 56.57592 0.94184 16.29295 0.52413 15.11622 0.48627 57031.045699 0.000379 0.26955 0.00969 1.00000 0 60.67855 1.00884 56.63577 0.94162 16.35588 0.52108 15.26618 0.48636 57031.046431 0.000353 0.29302 0.01061 1.00000 0 59.80963 1.03575 55.82467 0.96674 17.52528 0.55736 16.35761 0.52023 57031.047363 0.000579 0.28048 0.00818 0.99540 0 59.58466 0.80930 55.61179 0.75534 16.71235 0.43140 15.59806 0.40264 57031.111310 0.000472 0.23325 0.00838 1.00000 0 58.55870 0.91151 51.77738 0.80592 13.65868 0.44242 12.07525 0.39110 57031.112230 0.000448 0.25632 0.00926 1.00000 0 55.50124 0.90237 49.83085 0.81018 14.22628 0.45873 12.77152 0.41182 57031.113106 0.000428 0.26224 0.00947 1.00000 0 57.55251 0.94430 51.01438 0.83698 15.09281 0.48552 13.38202 0.43044 57031.114055 0.000521 0.23196 0.00790 1.00000 0 57.75504 0.85445 51.66798 0.76439 13.39686 0.41111 11.98380 0.36775
