/* ** ** 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 58786.601387 0.000370 0.14087 0.01102 0.99219 0 34.17397 0.92761 22.66526 0.60411 4.81423 0.35325 3.12757 0.22502 58786.602209 0.000451 0.13549 0.01049 0.98077 0 29.94763 0.80171 18.89911 0.50470 4.05762 0.29488 2.57108 0.18670 58786.603057 0.000396 0.14123 0.01106 0.98540 0 30.05835 0.82012 20.52980 0.56011 4.24506 0.31154 2.90173 0.21297 58786.603881 0.000428 0.13315 0.01018 0.99324 0 30.09834 0.78949 20.40597 0.53524 4.00764 0.28764 2.71568 0.19488 58786.604697 0.000388 0.14876 0.01129 0.97761 0 30.69876 0.84802 20.54371 0.56750 4.56664 0.32292 3.05853 0.21627 58786.605513 0.000428 0.13303 0.01029 0.99324 0 29.80931 0.79289 20.10603 0.53474 3.96567 0.28812 2.67602 0.19432 58786.606349 0.000408 0.14210 0.01110 1.00000 0 28.91316 0.79519 19.52181 0.53688 4.10867 0.30044 2.77697 0.20300 58786.607191 0.000434 0.13728 0.01052 0.97333 0 29.53775 0.77735 19.86934 0.52291 4.05493 0.29168 2.72056 0.19573 58786.608112 0.000486 0.12108 0.00936 0.97619 0 29.20233 0.72996 19.72555 0.49308 3.53594 0.25851 2.38752 0.17453 58786.608994 0.000396 0.13913 0.01097 1.00000 0 30.40870 0.83888 20.45647 0.56435 4.23087 0.31256 2.84606 0.21028 58786.609807 0.000417 0.14154 0.01172 0.97222 0 27.98040 0.80066 18.93076 0.54163 3.96027 0.30767 2.67962 0.20815 58786.610652 0.000428 0.15368 0.01183 0.96622 0 28.97301 0.80661 19.44512 0.54137 4.45244 0.31948 2.98512 0.21427
