/* ** ** 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 55176.231414 0.000263 0.18737 0.01476 0.98901 0 26.60625 0.82539 23.43238 0.72693 4.98534 0.36109 4.39338 0.31815 55176.231929 0.000252 0.19419 0.01532 1.00000 0 26.18853 0.83628 23.39488 0.74707 5.08566 0.36681 4.54273 0.32765 55176.232441 0.000260 0.18137 0.01418 1.00000 0 27.57370 0.84440 24.35153 0.74567 5.00096 0.35980 4.41356 0.31751 55176.232971 0.000269 0.17987 0.01396 0.98925 0 27.51719 0.83415 24.10590 0.73071 4.94964 0.35377 4.33736 0.30998 55176.233512 0.000272 0.18026 0.01412 0.98936 0 27.09193 0.82798 23.57268 0.72043 4.88356 0.35223 4.24965 0.30651 55176.234027 0.000243 0.19161 0.01536 0.98810 0 28.13418 0.89412 24.50823 0.77888 5.39086 0.39665 4.69599 0.34553 55176.234539 0.000269 0.17951 0.01421 1.00000 0 27.07927 0.83472 23.57572 0.72672 4.86109 0.35435 4.23212 0.30851 55176.235043 0.000234 0.20156 0.01572 1.00000 0 28.05140 0.90578 24.57120 0.79335 5.65394 0.40147 4.94881 0.35136 55176.235529 0.000252 0.18729 0.01500 1.00000 0 27.08634 0.85508 23.93065 0.75537 5.07287 0.37333 4.48008 0.32964 55176.236052 0.000272 0.17524 0.01352 1.00000 0 27.76302 0.83740 24.33466 0.73392 4.86527 0.34545 4.26440 0.30277 55176.236559 0.000234 0.20372 0.01623 1.00000 0 27.38547 0.89637 23.84032 0.78034 5.57899 0.40508 4.85680 0.35264 55176.237054 0.000260 0.18871 0.01488 0.98889 0 27.06052 0.84426 23.54539 0.73459 5.10646 0.36979 4.44274 0.32173 55176.237560 0.000246 0.19724 0.01535 0.96471 0 28.40660 0.88754 24.79935 0.77479 5.60301 0.39943 4.89074 0.34864 55176.238058 0.000252 0.18860 0.01519 0.97701 0 27.69573 0.87384 24.22539 0.76421 5.22334 0.38696 4.56413 0.33807 55176.238561 0.000252 0.20216 0.01581 0.98851 0 26.49579 0.85151 23.06658 0.74130 5.35629 0.38182 4.66326 0.33242 55176.239053 0.000240 0.19107 0.01496 1.00000 0 28.68361 0.90424 25.04231 0.78940 5.48048 0.39271 4.78354 0.34274 55176.239559 0.000266 0.17505 0.01376 0.98913 0 28.17353 0.84958 24.72919 0.74575 4.93190 0.35808 4.32308 0.31388 55176.240098 0.000272 0.17940 0.01448 0.98936 0 26.53310 0.81984 23.14587 0.71514 4.76017 0.35497 4.15198 0.30961 55176.240636 0.000266 0.18008 0.01421 1.00000 0 27.28814 0.84276 23.74674 0.73339 4.91393 0.35678 4.27609 0.31047 55176.241148 0.000246 0.19289 0.01534 1.00000 0 27.19645 0.86516 24.01678 0.76394 5.24586 0.38235 4.63044 0.33754 55176.241634 0.000240 0.19780 0.01576 1.00000 0 27.38737 0.88100 23.98722 0.77157 5.41711 0.39493 4.74202 0.34568 55176.242123 0.000249 0.19643 0.01518 1.00000 0 27.62549 0.86802 24.19901 0.76028 5.42660 0.38299 4.75644 0.33567
