/* ** ** 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 60104.947004 0.000541 0.17619 0.01411 0.98930 0 16.96034 0.53103 12.02883 0.37509 2.98824 0.22024 2.11732 0.15542 60104.948072 0.000527 0.15254 0.01224 0.98901 0 18.38852 0.52701 14.07651 0.40329 2.80503 0.21014 2.14567 0.16070 60104.949047 0.000448 0.19479 0.01548 0.99355 0 17.19530 0.55382 13.14465 0.42339 3.34953 0.24332 2.55426 0.18550 60104.949990 0.000495 0.17259 0.01329 0.97076 0 18.37439 0.54831 13.99291 0.41755 3.17127 0.22521 2.41471 0.17145 60104.950988 0.000503 0.16747 0.01331 0.99425 0 17.57528 0.52637 13.46118 0.40303 2.94335 0.21671 2.25260 0.16580 60104.951987 0.000495 0.17727 0.01406 0.97661 0 17.10642 0.52507 13.21204 0.40548 3.03249 0.22176 2.34448 0.17141 60104.952936 0.000454 0.17581 0.01385 0.98726 0 18.72968 0.57055 14.46692 0.44060 3.29278 0.23917 2.53778 0.18430 60104.953856 0.000466 0.17948 0.01445 1.00000 0 17.22527 0.54303 13.41114 0.42278 3.09153 0.22905 2.40914 0.17852 60104.954790 0.000469 0.18140 0.01442 0.99383 0 17.24854 0.53622 13.41709 0.41710 3.12880 0.22885 2.43185 0.17779 60104.955829 0.000570 0.14329 0.01101 0.98985 0 18.43072 0.50939 14.22144 0.39303 2.64085 0.18926 2.03596 0.14589 60104.957366 0.000966 0.17306 0.00978 0.99102 0 17.41867 0.37968 13.48354 0.29387 3.01454 0.15717 2.33600 0.12183
