/* ** ** 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 58225.064995 0.000472 0.16743 0.01391 0.96933 0 22.65722 0.69768 14.26812 0.43913 3.79354 0.29260 2.38644 0.18404 58225.065904 0.000437 0.19125 0.01552 0.97351 0 20.81186 0.67547 13.81601 0.44841 3.98028 0.29602 2.64042 0.19635 58225.066809 0.000469 0.18041 0.01445 0.98765 0 20.38002 0.63624 13.58458 0.42396 3.67673 0.27126 2.44976 0.18047 58225.067709 0.000431 0.17891 0.01402 1.00000 0 22.52988 0.69077 14.81768 0.45417 4.03090 0.29081 2.65248 0.19131 58225.068606 0.000466 0.16950 0.01321 0.98758 0 22.25638 0.65803 14.73423 0.43547 3.77249 0.27209 2.48565 0.17928 58225.069529 0.000457 0.18056 0.01433 0.99367 0 21.13686 0.65288 13.80476 0.42636 3.81640 0.27906 2.49418 0.18230 58225.070421 0.000434 0.18611 0.01454 0.99333 0 21.67917 0.67445 14.34427 0.44622 4.03480 0.28905 2.66466 0.19092 58225.071297 0.000443 0.16955 0.01316 0.99346 0 23.19227 0.68454 15.45084 0.45590 3.93218 0.28224 2.62648 0.18846 58225.072212 0.000472 0.16620 0.01296 0.98773 0 21.98190 0.64557 14.81664 0.43509 3.65335 0.26392 2.46838 0.17828 58225.073126 0.000443 0.17887 0.01419 0.98693 0 21.95704 0.66945 14.55830 0.44382 3.92752 0.28760 2.60780 0.19085 58225.074052 0.000483 0.16674 0.01279 0.98204 0 21.92491 0.63679 14.61955 0.42451 3.65576 0.25959 2.44423 0.17354 58225.074978 0.000443 0.17488 0.01375 0.98693 0 22.00322 0.66564 14.89396 0.45045 3.84791 0.27935 2.60532 0.18916 58225.075886 0.000466 0.16447 0.01301 0.98758 0 21.83764 0.64305 14.96662 0.44065 3.59168 0.26364 2.46399 0.18081 58225.076844 0.000492 0.15315 0.01178 0.98235 0 23.21330 0.65013 15.46467 0.43295 3.55514 0.25464 2.37746 0.17035 58225.077785 0.000448 0.16844 0.01337 0.98710 0 22.24808 0.66136 15.11294 0.44915 3.74758 0.27579 2.54752 0.18744 58225.078621 0.000388 0.19299 0.01509 0.97761 0 23.67258 0.74002 15.67926 0.48999 4.56867 0.32741 3.03080 0.21716 58225.079477 0.000469 0.16659 0.01288 1.00000 0 21.42240 0.63102 14.78191 0.43538 3.56879 0.25504 2.46320 0.17604 58225.080389 0.000443 0.17320 0.01361 0.99346 0 21.95350 0.65967 14.93806 0.44876 3.80238 0.27597 2.58818 0.18792 58225.081384 0.000553 0.17556 0.01207 0.99476 0 23.30116 0.61486 15.60946 0.41180 4.09083 0.25972 2.73776 0.17382
