/* ** ** 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 60027.097297 0.000301 0.15264 0.01173 1.00000 0 27.06845 0.75469 25.02459 0.69771 4.13163 0.29578 3.81940 0.27342 60027.097861 0.000263 0.18595 0.01467 0.98901 0 25.75855 0.80106 23.50467 0.73096 4.78978 0.34715 4.37522 0.31712 60027.098457 0.000333 0.14726 0.01135 0.98261 0 26.02868 0.71400 23.79799 0.65278 3.83308 0.27605 3.49995 0.25211 60027.099128 0.000339 0.13847 0.01077 1.00000 0 26.52407 0.71798 24.16201 0.65405 3.67285 0.26791 3.35082 0.24438 60027.099785 0.000318 0.15619 0.01182 0.97273 0 26.60486 0.74238 24.18310 0.67475 4.15548 0.29239 3.78199 0.26610 60027.100416 0.000312 0.15240 0.01185 0.99074 0 26.10882 0.73596 24.14833 0.68070 3.97886 0.28839 3.68009 0.26673 60027.101081 0.000353 0.14161 0.01118 0.98361 0 24.88397 0.67836 22.90329 0.62429 3.52390 0.26112 3.24064 0.24015 60027.101735 0.000301 0.16502 0.01295 0.97115 0 25.89215 0.75101 23.48901 0.68127 4.27260 0.31162 3.88164 0.28309 60027.102349 0.000312 0.13853 0.01114 0.99074 0 28.17219 0.76531 25.75894 0.69970 3.90276 0.29549 3.56730 0.27012 60027.102982 0.000321 0.15518 0.01212 0.98198 0 25.76254 0.72711 23.41435 0.66069 3.99771 0.29113 3.63607 0.26471 60027.103593 0.000289 0.16971 0.01323 1.00000 0 25.40579 0.75572 23.28745 0.69265 4.31153 0.31062 3.95494 0.28488 60027.104383 0.000501 0.15536 0.00974 0.98904 0 25.80144 0.58138 23.41249 0.52753 4.00862 0.23444 3.63745 0.21266 60027.164289 0.000321 0.16773 0.01321 0.97297 0 25.17190 0.73829 21.62730 0.63432 4.22218 0.30847 3.62655 0.26496 60027.164905 0.000295 0.17828 0.01413 0.99020 0 25.62387 0.78255 21.89641 0.66863 4.56819 0.33413 3.89974 0.28527 60027.165513 0.000312 0.17071 0.01318 0.99074 0 25.33823 0.75708 21.82777 0.65224 4.32542 0.30789 3.72772 0.26531 60027.166248 0.000422 0.19037 0.01214 0.99315 0 25.36864 0.64499 21.81462 0.55460 4.82945 0.28257 4.15184 0.24288
