/* ** ** 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 56074.713589 0.000940 0.09374 0.00698 0.98154 0 15.61965 0.34037 13.34476 0.29072 1.46413 0.10424 1.25027 0.08900 56074.715533 0.001004 0.08271 0.00641 0.98559 0 15.80250 0.32970 13.64699 0.28473 1.30708 0.09751 1.12869 0.08421 56074.716844 0.000307 0.07224 0.01038 0.99057 0 15.85447 0.59739 13.73279 0.51744 1.14533 0.15883 0.99213 0.13758 56074.717998 0.000848 0.09845 0.00758 0.98976 0 15.76318 0.35745 13.64757 0.30947 1.55186 0.11423 1.34371 0.09891 56074.719824 0.000978 0.08672 0.00660 0.99408 0 15.51025 0.33039 13.43597 0.28621 1.34508 0.09835 1.16520 0.08520 56074.722538 0.001736 0.09353 0.00514 0.98333 0 15.43911 0.24762 13.36610 0.21437 1.44408 0.07595 1.25070 0.06578
