/* ** ** 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 56702.365202 0.000521 0.23426 0.00837 1.00000 0 52.48087 0.81820 47.16489 0.73523 12.29391 0.39514 11.04900 0.35510 56702.365841 0.000119 0.20451 0.01584 1.00000 0 53.78901 1.76041 48.49892 1.58727 11.00055 0.77209 9.91895 0.69617 56702.366504 0.000544 0.21630 0.00781 1.00000 0 54.79818 0.82599 48.28457 0.72780 11.85302 0.38895 10.44340 0.34268 56702.367603 0.000556 0.21395 0.00762 0.98958 0 54.78310 0.81490 48.69650 0.72432 11.72074 0.37908 10.41552 0.33679 56702.368685 0.000527 0.21981 0.00783 1.00000 0 55.78022 0.84552 49.53852 0.75084 12.26116 0.39546 10.88946 0.35123 56702.369762 0.000550 0.21444 0.00763 1.00000 0 54.52405 0.81518 48.69733 0.72798 11.69222 0.37766 10.43661 0.33712 56702.370838 0.000527 0.21788 0.00775 1.00000 0 56.49094 0.85404 50.16236 0.75834 12.30843 0.39616 10.93349 0.35191 56702.371900 0.000535 0.21728 0.00780 0.99459 0 55.55830 0.83466 49.35995 0.74149 12.07185 0.39364 10.72408 0.34974 56702.372950 0.000515 0.21707 0.00787 0.99438 0 56.58272 0.85489 50.86620 0.76844 12.28236 0.40468 11.04190 0.36382 56702.373986 0.000521 0.22739 0.00817 1.00000 0 53.83842 0.83109 48.18779 0.74385 12.24229 0.39728 10.95561 0.35553 56702.374742 0.000234 0.20065 0.01121 1.00000 0 54.81683 1.24938 49.09082 1.11890 10.99923 0.56114 9.84715 0.50236 56702.375783 0.000807 0.21650 0.00626 1.00000 0 54.90245 0.67196 49.32489 0.60369 11.88655 0.31122 10.67936 0.27959
