/* ** ** 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 58471.985167 0.000466 0.13924 0.01098 0.99379 0 19.36129 0.52321 17.42715 0.47087 2.69584 0.19974 2.42407 0.17964 58471.986033 0.000399 0.15323 0.01225 1.00000 0 20.14274 0.57817 18.24530 0.52372 3.08647 0.23024 2.79725 0.20870 58471.986883 0.000451 0.14237 0.01096 0.97436 0 20.04371 0.54045 18.26130 0.49239 2.85363 0.20587 2.59983 0.18755 58471.987705 0.000370 0.17249 0.01363 0.98438 0 19.86088 0.59480 18.02020 0.53965 3.42579 0.25044 3.10725 0.22719 58471.988428 0.000353 0.18180 0.01414 1.00000 0 20.00848 0.61332 18.01686 0.55228 3.63755 0.25997 3.27056 0.23377 58471.989239 0.000457 0.14112 0.01084 1.00000 0 19.55374 0.52726 17.81352 0.48033 2.75936 0.19855 2.51378 0.18088 58471.990124 0.000428 0.14895 0.01170 0.98649 0 19.85341 0.55454 18.00250 0.50280 2.95720 0.21707 2.68278 0.19695 58471.990972 0.000420 0.15516 0.01223 0.99310 0 19.32417 0.55393 17.51740 0.50216 2.99836 0.22008 2.72004 0.19968 58471.991863 0.000472 0.13918 0.01075 0.98773 0 19.36719 0.51899 17.64323 0.47279 2.69553 0.19525 2.45557 0.17787 58471.992772 0.000437 0.14385 0.01109 0.98675 0 20.32239 0.55435 18.42813 0.50266 2.92342 0.21088 2.65218 0.19133 58471.993608 0.000399 0.17415 0.01351 0.97101 0 18.68042 0.55461 17.01320 0.50511 3.25315 0.23312 2.96273 0.21231 58471.994560 0.000553 0.15197 0.01026 0.98953 0 19.86335 0.48684 18.08889 0.44335 3.01863 0.18996 2.74896 0.17299
