/* ** ** 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 59314.939534 0.000530 0.14233 0.01083 0.99454 0 17.30666 0.46271 15.47931 0.41380 2.46324 0.17554 2.20225 0.15692 59314.940654 0.000584 0.13633 0.01055 0.99010 0 15.98351 0.42169 14.46466 0.38162 2.17896 0.15860 1.97185 0.14352 59314.941800 0.000561 0.14201 0.01082 0.97938 0 16.30751 0.43765 14.75437 0.39597 2.31586 0.16516 2.09522 0.14942 59314.942836 0.000475 0.16289 0.01258 0.97561 0 16.85440 0.48128 15.25238 0.43554 2.74542 0.19696 2.48449 0.17824 59314.943941 0.000631 0.12228 0.00932 0.99083 0 16.55150 0.41548 14.97554 0.37592 2.02384 0.14557 1.83109 0.13171 59314.945179 0.000608 0.12004 0.00918 0.99048 0 17.47866 0.43490 15.81753 0.39356 2.09813 0.15182 1.89876 0.13739 59314.946342 0.000556 0.13915 0.01056 0.97917 0 16.89942 0.44575 15.29396 0.40341 2.35159 0.16728 2.12816 0.15139 59314.947483 0.000584 0.12634 0.00980 0.99010 0 17.12129 0.44011 15.44360 0.39698 2.16307 0.15828 1.95182 0.14282 59314.948678 0.000611 0.12547 0.00945 0.98578 0 16.95664 0.42747 15.30846 0.38590 2.12749 0.15108 1.92009 0.13635 59314.949809 0.000521 0.14818 0.01142 0.99444 0 16.54770 0.45802 14.91068 0.41270 2.45210 0.17639 2.20958 0.15893 59314.951204 0.000874 0.14542 0.00879 0.99007 0 16.44843 0.34996 14.86337 0.31623 2.39191 0.13535 2.16126 0.12229
