/* ** ** 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 59369.899136 0.000469 0.16569 0.01286 0.98765 0 16.30736 0.48140 14.95898 0.44153 2.70204 0.19395 2.47694 0.17777 59369.900154 0.000550 0.13686 0.01047 0.98947 0 16.61760 0.44135 15.40104 0.40905 2.27423 0.16322 2.10803 0.15129 59369.901248 0.000544 0.14329 0.01091 0.97340 0 16.59877 0.44535 15.35070 0.41185 2.37845 0.16940 2.19847 0.15658 59369.902304 0.000512 0.14338 0.01148 0.98870 0 16.81689 0.46548 15.26342 0.42249 2.41117 0.18108 2.18993 0.16443 59369.903337 0.000521 0.13800 0.01067 0.99444 0 17.51568 0.47075 15.92065 0.42783 2.41719 0.17524 2.19779 0.15931 59369.904417 0.000558 0.13364 0.01043 0.98964 0 16.76853 0.44376 15.33126 0.40570 2.24087 0.16448 2.04739 0.15025 59369.905476 0.000495 0.15887 0.01251 0.98830 0 15.90662 0.45988 14.57076 0.42118 2.52711 0.18505 2.31065 0.16918 59369.906503 0.000532 0.15104 0.01153 0.98370 0 15.85321 0.44253 14.60564 0.40771 2.39439 0.17017 2.20561 0.15673 59369.907489 0.000454 0.16512 0.01284 0.99363 0 16.74870 0.48772 15.32070 0.44611 2.76548 0.19945 2.53114 0.18256 59369.908829 0.000885 0.15190 0.00858 0.99346 0 17.42686 0.35918 15.92784 0.32825 2.64714 0.13929 2.42097 0.12738
