/* ** ** 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 58216.900617 0.000422 0.15614 0.01227 0.98630 0 19.43740 0.54917 17.42560 0.49229 3.03497 0.22265 2.72080 0.19963 58216.901473 0.000434 0.16242 0.01275 1.00000 0 18.02087 0.52663 16.17200 0.47260 2.92700 0.21334 2.62405 0.19127 58216.902359 0.000451 0.16240 0.01255 0.98077 0 17.89487 0.51263 16.05682 0.45996 2.90604 0.20849 2.60938 0.18722 58216.903195 0.000385 0.18320 0.01421 1.00000 0 18.34390 0.56418 16.37934 0.50373 3.36065 0.23922 2.99890 0.21345 58216.903988 0.000408 0.17420 0.01361 0.99291 0 18.25776 0.54619 16.28628 0.48712 3.18042 0.22965 2.83874 0.20502 58216.904902 0.000506 0.13691 0.01057 0.99429 0 18.44605 0.48962 16.69115 0.44304 2.52538 0.18311 2.28514 0.16569 58216.905843 0.000434 0.15730 0.01231 0.98667 0 18.68480 0.53265 16.90764 0.48199 2.93905 0.21423 2.65951 0.19385 58216.906734 0.000457 0.15400 0.01199 0.99367 0 18.25624 0.51748 16.45503 0.46642 2.81141 0.20385 2.53257 0.18363 58216.907619 0.000428 0.16546 0.01276 1.00000 0 18.21617 0.53063 16.47250 0.47984 3.01399 0.21515 2.72461 0.19449 58216.908473 0.000425 0.17196 0.01338 0.99320 0 17.61793 0.52291 15.83522 0.46995 3.02950 0.21793 2.72077 0.19572 58216.909399 0.000501 0.14810 0.01151 0.98266 0 17.28005 0.47774 15.62955 0.43211 2.55926 0.18582 2.31421 0.16801 58216.910336 0.000437 0.16443 0.01288 1.00000 0 17.51089 0.51389 15.84541 0.46501 2.87926 0.20904 2.60541 0.18916 58216.911196 0.000422 0.16307 0.01248 0.97945 0 18.99727 0.54339 17.19051 0.49171 3.09783 0.21994 2.80320 0.19902 58216.912414 0.000796 0.16963 0.00949 0.99309 0 18.10511 0.38774 16.34106 0.34995 3.07124 0.15865 2.77422 0.14330 58216.968666 0.000422 0.15580 0.01229 0.98630 0 18.98967 0.54182 17.38015 0.49590 2.95857 0.21751 2.70804 0.19907 58216.969496 0.000408 0.17479 0.01366 1.00000 0 17.79283 0.53840 16.05477 0.48574 3.11008 0.22419 2.80363 0.20212 58216.970387 0.000483 0.14212 0.01113 0.98204 0 18.49274 0.50194 16.72488 0.45388 2.62820 0.19316 2.37779 0.17480 58216.971525 0.000654 0.15044 0.00981 0.97345 0 18.45311 0.43275 16.64443 0.39030 2.77604 0.16882 2.50715 0.15248
