/* ** ** 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 59746.199839 0.000619 0.11947 0.00918 0.99533 0 17.14819 0.42792 15.46799 0.38593 2.04866 0.14882 1.84668 0.13412 59746.201127 0.000668 0.11005 0.00841 0.99134 0 17.35398 0.41561 15.63104 0.37434 1.90987 0.13868 1.71765 0.12475 59746.202519 0.000723 0.09727 0.00744 0.99200 0 17.98255 0.40579 16.22244 0.36608 1.74919 0.12788 1.57867 0.11543 59746.203931 0.000689 0.10568 0.00790 0.99580 0 17.70644 0.41286 16.00766 0.37324 1.87123 0.13286 1.69130 0.12009 59746.205334 0.000715 0.10201 0.00764 0.99190 0 17.70566 0.40540 16.04443 0.36736 1.80624 0.12878 1.63678 0.11670 59746.206804 0.000755 0.09667 0.00719 0.97318 0 18.01184 0.39599 16.32327 0.35887 1.74126 0.12364 1.57811 0.11205 59746.208274 0.000715 0.10581 0.00808 0.99595 0 16.67527 0.39436 15.11001 0.35734 1.76448 0.12815 1.59895 0.11613 59746.210033 0.001045 0.11378 0.00675 0.98615 0 17.64998 0.33462 15.99129 0.30317 2.00826 0.11289 1.81957 0.10228
