/* ** ** 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 59208.144242 0.000804 0.16187 0.01280 0.98921 0 15.21931 0.44615 8.76852 0.25599 2.46358 0.18090 1.41520 0.10379 59208.145871 0.000825 0.16879 0.01307 0.97544 0 15.42534 0.45304 8.44224 0.24793 2.60369 0.18659 1.42622 0.10219 59208.147477 0.000781 0.18235 0.01407 0.97037 0 15.26609 0.46224 8.36418 0.25325 2.78375 0.19749 1.52528 0.10821 59208.148996 0.000738 0.18903 0.01480 0.99216 0 15.21293 0.47960 8.28763 0.26123 2.87574 0.20607 1.56716 0.11229 59208.150515 0.000781 0.16572 0.01271 0.98148 0 16.68350 0.48271 9.11699 0.26376 2.76475 0.19632 1.51163 0.10732 59208.151941 0.000645 0.18910 0.01473 0.98655 0 17.46633 0.54007 9.60168 0.29687 3.30285 0.23621 1.81569 0.12986 59208.153359 0.000773 0.16329 0.01234 0.98127 0 17.77604 0.50195 9.71543 0.27433 2.90270 0.20347 1.58580 0.11116
