/* ** ** 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 57405.448918 0.000305 0.20551 0.03172 1.00000 1 23.82510 1.51541 4.77806 0.30388 4.89623 0.68847 0.97784 0.13750 57405.449543 0.000320 0.23962 0.03809 1.00000 1 18.70260 1.33832 3.77802 0.27034 4.48144 0.63607 0.90608 0.12860 57405.450807 0.000944 0.23510 0.02078 1.00000 1 20.57303 0.80046 4.20029 0.16342 4.83664 0.38386 0.98774 0.07839 57405.452114 0.000363 0.19302 0.02974 0.96000 1 21.46210 1.33204 4.37521 0.27153 4.14270 0.58424 0.84447 0.11909 57405.453189 0.000712 0.23081 0.02373 0.95918 1 21.02703 0.93254 4.29747 0.19059 4.85333 0.45008 0.99293 0.09208 57405.454307 0.000407 0.17515 0.02686 1.00000 1 20.40483 1.22412 4.17307 0.25035 3.57386 0.50432 0.73101 0.10315 57405.455193 0.000479 0.22976 0.02843 1.00000 1 20.97251 1.13906 4.30444 0.23378 4.81864 0.53567 0.98791 0.10982 57405.456007 0.000334 0.18526 0.02865 1.00000 1 23.06374 1.43913 4.73968 0.29573 4.27275 0.60470 0.87830 0.12430 57405.456689 0.000349 0.19808 0.03100 0.95833 1 21.32944 1.35841 4.34807 0.27690 4.22502 0.60407 0.86091 0.12308 57405.457372 0.000334 0.21237 0.03366 1.00000 1 19.80942 1.33557 4.04869 0.27296 4.20695 0.60355 0.85803 0.12311 57405.458069 0.000363 0.21016 0.03198 0.96000 1 20.41848 1.29658 4.17797 0.26530 4.29108 0.59343 0.87781 0.12140 57405.458796 0.000363 0.18743 0.02989 1.00000 1 20.21010 1.29042 4.13910 0.26428 3.78793 0.55353 0.77610 0.11342 57405.459783 0.000625 0.23118 0.02607 0.97728 1 19.85683 0.97585 4.08638 0.20082 4.59044 0.46586 0.94401 0.09581
