/* ** ** 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 55594.203905 0.000521 0.10121 0.01522 0.98889 0 6.47611 0.29404 5.50989 0.25012 0.65543 0.09395 0.55687 0.07980 55594.205048 0.000622 0.08547 0.01247 0.98605 0 6.50291 0.26766 5.64182 0.23222 0.55582 0.07783 0.48193 0.06748 55594.206330 0.000660 0.08242 0.01229 0.97368 0 6.32972 0.25989 5.41821 0.22245 0.52169 0.07476 0.44650 0.06398 55594.207291 0.000301 0.07434 0.01779 0.97115 0 5.98957 0.37229 5.19842 0.32311 0.44528 0.10292 0.38637 0.08930 55594.208202 0.000611 0.08807 0.01332 0.97156 0 6.31283 0.26733 5.42792 0.22984 0.55595 0.08075 0.47844 0.06947 55594.209392 0.000579 0.09186 0.01414 0.99500 0 6.20552 0.27311 5.35149 0.23554 0.57003 0.08408 0.49245 0.07265 55594.210636 0.000666 0.08520 0.01258 0.96087 0 6.28115 0.25590 5.37098 0.21878 0.53516 0.07593 0.45759 0.06491 55594.211990 0.000689 0.08296 0.01251 0.95378 0 6.11321 0.25056 5.20379 0.21327 0.50715 0.07362 0.43207 0.06274 55594.213266 0.000587 0.07995 0.01311 0.97537 0 6.40512 0.27558 5.42799 0.23352 0.51209 0.08104 0.43423 0.06869
