/* ** ** 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 57197.921909 0.000272 0.16469 0.01260 1.00000 0 34.54438 0.99603 26.00026 0.74959 5.68910 0.40318 4.28155 0.30336 57197.922447 0.000266 0.15878 0.01231 1.00000 0 36.08459 1.03833 27.00926 0.77699 5.72942 0.41241 4.29507 0.30912 57197.922974 0.000260 0.16882 0.01296 0.98889 0 35.68309 1.04201 26.64741 0.77810 6.02385 0.42788 4.49958 0.31961 57197.923497 0.000263 0.16898 0.01294 0.98901 0 36.27126 1.06379 26.32768 0.77214 6.12916 0.43344 4.45186 0.31479 57197.924010 0.000249 0.17971 0.01401 0.98837 0 35.02948 1.06080 26.07939 0.78973 6.29525 0.45236 4.68293 0.33648 57197.924533 0.000275 0.17486 0.01354 0.97895 0 32.95059 0.97911 24.42752 0.72582 5.76164 0.41185 4.27263 0.30533 57197.925080 0.000272 0.16366 0.01258 1.00000 0 35.19728 1.01943 25.94178 0.75125 5.76044 0.41024 4.23892 0.30186 57197.925601 0.000249 0.18397 0.01462 1.00000 0 34.14230 1.05862 24.85623 0.77065 6.28113 0.45975 4.57475 0.33486 57197.926081 0.000231 0.19258 0.01511 1.00000 0 35.50110 1.11984 25.85649 0.81549 6.83668 0.49133 4.97562 0.35751 57197.926556 0.000243 0.19907 0.01538 1.00000 0 33.32382 1.05518 24.50891 0.77590 6.63361 0.46745 4.88422 0.34414 57197.927056 0.000258 0.17060 0.01313 0.98876 0 36.46228 1.07689 26.70163 0.78842 6.22050 0.44195 4.55071 0.32324 57197.927548 0.000234 0.18800 0.01474 0.98765 0 36.72026 1.13992 26.26461 0.81528 6.90352 0.49686 4.93933 0.35548 57197.928081 0.000298 0.14787 0.01142 1.00000 0 35.18473 0.97239 26.11747 0.72172 5.20284 0.37527 3.85384 0.27789 57197.928630 0.000252 0.17869 0.01395 0.98851 0 34.83742 1.05445 25.74477 0.77919 6.22501 0.44802 4.59473 0.33068 57197.929140 0.000258 0.17591 0.01368 1.00000 0 34.64806 1.03993 25.65584 0.77001 6.09485 0.43714 4.50508 0.32317 57197.929603 0.000205 0.22190 0.01789 1.00000 0 34.60383 1.18525 24.80218 0.84954 7.67856 0.56057 5.50325 0.40175 57197.930069 0.000260 0.15979 0.01235 1.00000 0 37.42945 1.07895 27.58910 0.79516 5.98071 0.42889 4.40279 0.31575 57197.930572 0.000243 0.18031 0.01406 1.00000 0 35.11361 1.07425 26.17681 0.80080 6.33117 0.45410 4.71727 0.33830 57197.931073 0.000258 0.17451 0.01347 1.00000 0 35.37606 1.04957 26.00106 0.77138 6.17346 0.43978 4.52989 0.32269 57197.931573 0.000243 0.18108 0.01421 0.98810 0 36.24215 1.10760 26.26005 0.80236 6.56286 0.47438 4.75834 0.34400 57197.932218 0.000402 0.16589 0.01056 0.97842 0 36.45864 0.85880 26.36538 0.62099 6.04805 0.35758 4.37251 0.25850
