/* ** ** 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 56352.367381 0.000605 0.13621 0.01044 0.99043 0 15.30461 0.40415 14.05226 0.37108 2.08467 0.14998 1.91186 0.13755 56352.368541 0.000556 0.15020 0.01165 0.99479 0 14.92100 0.41558 13.73550 0.38256 2.24117 0.16218 2.06344 0.14932 56352.369594 0.000498 0.16292 0.01258 1.00000 0 15.43219 0.44755 14.17045 0.41093 2.51424 0.17990 2.31042 0.16527 56352.370656 0.000564 0.14305 0.01099 0.98462 0 15.73826 0.42367 14.40363 0.38772 2.25141 0.16201 2.06122 0.14830 56352.371747 0.000527 0.15469 0.01195 0.99451 0 15.50309 0.43659 14.12103 0.39764 2.39811 0.17255 2.18649 0.15731 56352.372861 0.000587 0.13565 0.01051 1.00000 0 15.57662 0.41430 14.25067 0.37904 2.11294 0.15379 1.93339 0.14072 56352.374050 0.000602 0.13470 0.01028 0.97596 0 16.08750 0.41829 14.55664 0.37848 2.16691 0.15549 1.95940 0.14061 56352.375271 0.000619 0.14025 0.01089 0.99065 0 14.44036 0.38956 13.21293 0.35642 2.02533 0.14741 1.85132 0.13475 56352.376431 0.000541 0.15057 0.01149 1.00000 0 15.82730 0.43701 14.25449 0.39358 2.38307 0.16960 2.14652 0.15276 56352.378063 0.001091 0.14636 0.00830 0.97878 0 14.93186 0.30021 13.57212 0.27288 2.18537 0.11596 1.98313 0.10523
