/* ** ** 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 56649.539841 0.000558 0.15534 0.01202 1.00000 0 14.64278 0.41576 13.23912 0.37587 2.27462 0.16373 2.05749 0.14810 56649.540880 0.000480 0.17958 0.01390 1.00000 0 14.76340 0.44872 13.37738 0.40660 2.65118 0.18875 2.40246 0.17104 56649.541942 0.000582 0.14731 0.01157 0.98507 0 14.76655 0.40958 13.41899 0.37221 2.17523 0.15980 1.97738 0.14528 56649.543039 0.000515 0.16519 0.01318 0.97753 0 14.94605 0.44043 13.46414 0.39677 2.46901 0.18314 2.22793 0.16526 56649.544124 0.000570 0.15588 0.01216 0.98985 0 14.21160 0.40308 12.93931 0.36699 2.21535 0.16097 2.01658 0.14653 56649.545278 0.000584 0.15327 0.01195 0.98515 0 14.15785 0.39958 12.89304 0.36388 2.16991 0.15768 1.97605 0.14359 56649.546473 0.000611 0.14409 0.01130 0.99052 0 14.27769 0.39305 13.00079 0.35790 2.05729 0.15115 1.87330 0.13763 56649.547619 0.000535 0.16754 0.01339 0.99459 0 13.85743 0.41184 12.57464 0.37372 2.32162 0.17220 2.10684 0.15628 56649.549416 0.001262 0.14618 0.00813 0.98165 0 13.37600 0.26367 12.18106 0.24011 1.95537 0.10165 1.78070 0.09257
