/* ** ** 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 55986.360640 0.000385 0.10301 0.01587 0.97744 0 8.19961 0.37832 7.26631 0.33524 0.84467 0.12417 0.74714 0.10980 55986.361401 0.000376 0.09874 0.01483 0.99231 0 8.74449 0.39458 7.75615 0.34996 0.86347 0.12366 0.76863 0.11009 55986.362162 0.000385 0.09203 0.01360 0.96992 0 9.65930 0.41246 8.43744 0.36029 0.88894 0.12571 0.77649 0.10981 55986.362923 0.000376 0.10011 0.01521 0.96154 0 8.79883 0.39453 7.84165 0.35159 0.88082 0.12787 0.78513 0.11390 55986.363768 0.000469 0.07901 0.01160 0.97531 0 9.02265 0.35700 8.02523 0.31749 0.71289 0.10083 0.63397 0.08966 55986.364624 0.000388 0.09730 0.01459 0.97761 0 8.76317 0.38742 7.80924 0.34523 0.85265 0.12217 0.75690 0.10841 55986.365374 0.000362 0.10898 0.01644 0.97600 0 8.37177 0.39613 7.43010 0.35159 0.91238 0.13067 0.81274 0.11641 55986.366123 0.000388 0.08856 0.01322 0.97015 0 9.73987 0.41015 8.62990 0.36340 0.86255 0.12355 0.76272 0.10925 55986.366887 0.000376 0.10396 0.01545 0.98462 0 8.50587 0.38964 7.50784 0.34387 0.88424 0.12506 0.78255 0.11067 55986.367709 0.000446 0.08751 0.01291 0.99351 0 8.37607 0.35211 7.48901 0.31481 0.73295 0.10366 0.65468 0.09259 55986.368559 0.000405 0.09157 0.01370 0.98571 0 8.84168 0.38361 7.86048 0.34102 0.80961 0.11596 0.71851 0.10291 55986.369352 0.000388 0.10127 0.01503 0.97761 0 8.54010 0.38464 7.56045 0.34052 0.86489 0.12232 0.76463 0.10814 55986.370047 0.000307 0.13886 0.02058 0.99057 0 8.17745 0.42730 7.14406 0.37330 1.13550 0.15747 0.99213 0.13758 55986.370802 0.000448 0.08306 0.01222 0.96774 0 9.13052 0.37139 8.03805 0.32693 0.75839 0.10726 0.66778 0.09444 55986.371652 0.000402 0.08488 0.01281 0.97842 0 9.68506 0.40367 8.49860 0.35420 0.82202 0.11925 0.72163 0.10469 55986.372442 0.000388 0.10840 0.01610 0.88060 0 9.00878 0.39939 7.89860 0.35014 0.97654 0.13847 0.85726 0.12155
