/* ** ** 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 57193.922081 0.000836 0.10010 0.00750 0.99308 0 15.04463 0.34012 13.83973 0.31288 1.50604 0.10759 1.38581 0.09898 57193.923609 0.000692 0.11576 0.00891 0.99582 0 15.51057 0.38170 14.21677 0.34982 1.79555 0.13090 1.64640 0.12000 57193.925009 0.000709 0.11759 0.00905 0.98776 0 14.95117 0.36904 13.75389 0.33947 1.75808 0.12816 1.61919 0.11801 57193.926494 0.000775 0.10828 0.00818 0.99254 0 15.01764 0.35329 13.73863 0.32318 1.62604 0.11671 1.48968 0.10694 57193.928036 0.000767 0.11182 0.00850 0.98868 0 14.70294 0.35194 13.49152 0.32293 1.64408 0.11866 1.50681 0.10872 57193.929543 0.000741 0.11193 0.00843 0.99219 0 15.09615 0.36164 13.98390 0.33499 1.68977 0.12071 1.56585 0.11184 57193.931039 0.000755 0.11019 0.00866 0.98467 0 14.90520 0.35824 13.58145 0.32640 1.64240 0.12282 1.49607 0.11186 57193.932906 0.001111 0.09805 0.00653 0.99219 0 14.96319 0.29282 13.86910 0.27140 1.46714 0.09344 1.36006 0.08662
