/* ** ** 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 57478.164808 0.000263 0.16855 0.01338 1.00000 0 27.84449 0.82788 25.38850 0.75482 4.69316 0.34548 4.28358 0.31512 57478.165354 0.000284 0.15051 0.01172 0.98980 0 29.48219 0.82506 27.09717 0.75832 4.43724 0.32256 4.07859 0.29648 57478.165901 0.000263 0.16302 0.01324 1.00000 0 28.33420 0.84227 25.78833 0.76659 4.61902 0.34901 4.20401 0.31763 57478.166439 0.000275 0.16387 0.01267 0.98947 0 28.12152 0.81720 25.77582 0.74904 4.60820 0.33016 4.22390 0.30263 57478.167001 0.000286 0.15416 0.01187 0.98990 0 28.82121 0.80584 26.42709 0.73890 4.44301 0.31878 4.07391 0.29229 57478.167533 0.000246 0.18824 0.01455 1.00000 0 27.52237 0.85894 25.05004 0.78174 5.18069 0.36635 4.71373 0.33331 57478.168057 0.000278 0.15565 0.01208 1.00000 0 29.00697 0.82398 26.59699 0.75552 4.51501 0.32607 4.13993 0.29898 57478.168630 0.000295 0.14842 0.01154 0.99020 0 28.62449 0.79811 26.24412 0.73174 4.24856 0.30844 3.89531 0.28279 57478.169191 0.000266 0.16039 0.01252 1.00000 0 29.22514 0.85172 26.79877 0.78101 4.68730 0.33939 4.29815 0.31122 57478.169758 0.000301 0.14323 0.01094 0.98077 0 29.79151 0.80176 27.31441 0.73510 4.26709 0.30494 3.91226 0.27958 57478.170320 0.000260 0.17053 0.01331 0.98889 0 28.40757 0.84751 26.04175 0.77693 4.84436 0.34937 4.44086 0.32027 57478.170829 0.000249 0.17506 0.01373 0.98837 0 28.98648 0.87371 26.57466 0.80101 5.07434 0.36742 4.65211 0.33685 57478.171327 0.000249 0.18119 0.01398 0.98837 0 28.88836 0.87503 26.28957 0.79620 5.23431 0.37128 4.76541 0.33797 57478.171853 0.000278 0.15707 0.01226 1.00000 0 28.66456 0.82076 26.08478 0.74681 4.50232 0.32684 4.09819 0.29752 57478.172403 0.000272 0.16032 0.01238 0.98936 0 29.23589 0.84057 26.63667 0.76587 4.68714 0.33584 4.26932 0.30588 57478.172930 0.000255 0.17040 0.01308 1.00000 0 29.30632 0.86929 26.86624 0.79691 4.99378 0.35365 4.57800 0.32421 57478.173445 0.000260 0.17888 0.01370 0.98889 0 27.88204 0.83621 25.55603 0.76645 4.98761 0.35146 4.57158 0.32214 57478.173948 0.000243 0.17605 0.01394 1.00000 0 28.88706 0.88027 26.48161 0.80697 5.08554 0.37165 4.66210 0.34070 57478.174475 0.000284 0.14282 0.01099 1.00000 0 31.15705 0.84978 28.37783 0.77391 4.44996 0.32010 4.05347 0.29158 57478.175036 0.000278 0.15502 0.01216 0.97917 0 29.88680 0.84327 27.02281 0.76245 4.63319 0.33921 4.18950 0.30655 57478.175577 0.000263 0.17126 0.01316 1.00000 0 28.36594 0.84709 25.85002 0.77192 4.85802 0.34404 4.42707 0.31352 57478.176127 0.000286 0.16237 0.01268 0.98990 0 27.12969 0.79232 24.84763 0.72569 4.40504 0.31895 4.03500 0.29216 57478.176732 0.000318 0.13193 0.01019 1.00000 0 29.58336 0.78007 27.11159 0.71489 3.90285 0.28334 3.57660 0.25965 57478.177412 0.000362 0.14658 0.01011 1.00000 0 29.52916 0.73136 26.93390 0.66710 4.32830 0.27868 3.94720 0.25414
