/* ** ** 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 57717.218631 0.000680 0.12909 0.01286 0.98298 0 8.62323 0.29010 7.70227 0.25911 1.11319 0.10439 0.99290 0.09311 57717.219713 0.000402 0.10174 0.01510 0.97122 0 8.09423 0.36473 7.29264 0.32861 0.82354 0.11647 0.74197 0.10493 57717.220570 0.000454 0.08239 0.01244 1.00000 0 8.41813 0.34977 7.58537 0.31516 0.69358 0.10066 0.62496 0.09070 57717.221397 0.000373 0.10221 0.01519 0.99225 0 8.49822 0.38910 7.65648 0.35056 0.86858 0.12284 0.78255 0.11067 57717.222072 0.000301 0.13751 0.02102 1.00000 0 7.69443 0.41064 6.93235 0.36997 1.05809 0.15158 0.95329 0.13656 57717.222977 0.000605 0.12984 0.01400 0.98086 0 8.34932 0.30302 7.52319 0.27304 1.08406 0.11009 0.97680 0.09920 57717.223923 0.000341 0.10846 0.01640 0.99153 0 8.75656 0.41426 7.88983 0.37325 0.94972 0.13640 0.85574 0.12290 57717.224638 0.000367 0.10994 0.01638 0.97638 0 8.15300 0.38273 7.34800 0.34494 0.89631 0.12676 0.80779 0.11424 57717.225338 0.000333 0.12021 0.01847 1.00000 0 7.87555 0.39711 7.09679 0.35784 0.94671 0.13739 0.85321 0.12382 57717.226039 0.000367 0.12458 0.01736 0.96306 0 8.46302 0.39415 7.62571 0.35515 1.05435 0.13844 0.95000 0.12474 57717.274883 0.000628 0.13816 0.01442 0.99078 0 8.21836 0.29899 7.14341 0.25986 1.13545 0.11111 0.98740 0.09662 57717.275951 0.000440 0.11785 0.01535 0.98684 0 8.54691 0.36444 7.47894 0.31890 1.00725 0.12398 0.88147 0.10850
