/* ** ** 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 54849.015481 0.000263 0.20450 0.01615 0.98901 0 25.25244 0.81112 21.82122 0.70091 5.16424 0.37252 4.46224 0.32188 54849.015996 0.000252 0.20652 0.01637 1.00000 0 25.27967 0.83057 22.01399 0.72327 5.22081 0.37656 4.54273 0.32765 54849.016505 0.000258 0.19609 0.01556 1.00000 0 26.34957 0.84396 22.58151 0.72321 5.16700 0.37509 4.42024 0.32094 54849.017003 0.000240 0.24102 0.01917 1.00000 0 22.98298 0.81628 19.94310 0.70829 5.53932 0.39428 4.80542 0.34204 54849.017657 0.000414 0.19246 0.01222 0.99901 0 25.55036 0.65204 22.18515 0.56616 4.91736 0.28579 4.26959 0.24814 54849.082164 0.000275 0.20509 0.01662 1.00000 0 24.63290 0.81056 19.94188 0.65607 5.05201 0.37413 4.08488 0.30241 54849.082774 0.000336 0.16985 0.01331 0.99138 0 25.19534 0.74690 20.15726 0.59736 4.27941 0.31041 3.42143 0.24834 54849.083437 0.000327 0.19214 0.01509 0.96460 0 23.63235 0.73618 18.87997 0.58813 4.54075 0.32739 3.62629 0.26149 54849.084018 0.000255 0.22418 0.01770 1.00000 0 25.23287 0.85729 20.33298 0.69083 5.65667 0.40315 4.55764 0.32484 54849.084557 0.000284 0.21978 0.01721 0.98980 0 23.46463 0.78475 18.88122 0.63142 5.15698 0.36521 4.15333 0.29412 54849.085089 0.000249 0.23592 0.01876 1.00000 0 24.63590 0.86853 19.77707 0.69715 5.81205 0.41434 4.66363 0.33240 54849.085613 0.000275 0.21992 0.01779 1.00000 0 23.40140 0.79881 18.78483 0.64124 5.14654 0.37739 4.12492 0.30255 54849.086206 0.000318 0.19066 0.01514 0.99091 0 23.72193 0.74583 18.93268 0.59524 4.52290 0.32968 3.61163 0.26317 54849.086825 0.000301 0.19549 0.01542 0.99038 0 24.90502 0.79192 19.75365 0.62812 4.86874 0.35148 3.85895 0.27864 54849.087430 0.000304 0.20565 0.01631 0.98095 0 23.45182 0.75583 18.77564 0.60507 4.82294 0.34960 3.86092 0.27986 54849.088011 0.000278 0.20918 0.01656 1.00000 0 24.45285 0.80768 19.78696 0.65355 5.11516 0.36794 4.13822 0.29763 54849.088573 0.000284 0.21284 0.01702 1.00000 0 23.47205 0.78858 18.84828 0.63318 4.99578 0.36262 4.01495 0.29142 54849.089152 0.000295 0.19441 0.01534 1.00000 0 25.00220 0.80003 19.92864 0.63773 4.86056 0.35048 3.87515 0.27944 54849.089701 0.000255 0.23849 0.01886 0.97727 0 24.49034 0.85259 19.53637 0.68009 5.84070 0.41468 4.66127 0.33092 54849.090257 0.000301 0.20922 0.01688 0.99038 0 22.76032 0.75544 18.07506 0.59996 4.76182 0.35019 3.78509 0.27837 54849.091108 0.000550 0.22358 0.01269 0.99474 0 23.27357 0.56385 18.63781 0.45153 5.20347 0.26707 4.16365 0.21370
