/* ** ** 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 57192.924686 0.000616 0.09989 0.00760 0.97183 0 21.63764 0.48431 18.98117 0.42484 2.16145 0.15712 1.89473 0.13774 57192.925844 0.000541 0.11836 0.00900 1.00000 0 20.58413 0.50716 17.93892 0.44198 2.43641 0.17528 2.12101 0.15257 57192.926917 0.000532 0.11987 0.00905 0.99457 0 20.98075 0.51899 18.18452 0.44979 2.51498 0.17950 2.18058 0.15562 57192.928057 0.000608 0.10924 0.00820 0.97619 0 20.40004 0.48075 17.76184 0.41852 2.22841 0.15881 1.94269 0.13845 57192.929290 0.000625 0.10378 0.00799 0.98611 0 20.50144 0.47692 17.66889 0.41099 2.12772 0.15614 1.83375 0.13454 57192.930525 0.000611 0.10653 0.00819 0.96209 0 20.80314 0.48425 18.05717 0.42031 2.21611 0.16239 1.92017 0.14070 57192.931648 0.000512 0.12498 0.00938 0.99435 0 20.91218 0.52764 18.21561 0.45959 2.61368 0.18483 2.27652 0.16097 57192.932730 0.000570 0.11508 0.00869 0.97970 0 20.41724 0.49243 17.88387 0.43131 2.34956 0.16815 2.05722 0.14719 57192.934371 0.001071 0.10689 0.00620 0.98421 0 19.74239 0.35360 17.19226 0.30791 2.11020 0.11640 1.83953 0.10147 57193.528298 0.000874 0.10034 0.00749 0.99338 0 15.53388 0.34965 13.32424 0.29991 1.55861 0.11092 1.33725 0.09515 57193.529918 0.000747 0.11620 0.00869 0.98062 0 15.83082 0.38210 13.64829 0.32942 1.83957 0.13024 1.58697 0.11236 57193.531524 0.000859 0.10439 0.00782 0.97643 0 15.46614 0.35256 13.18040 0.30043 1.61445 0.11516 1.37646 0.09819 57193.533894 0.001510 0.11054 0.00609 0.98084 0 15.33111 0.26473 13.05203 0.22536 1.69464 0.08870 1.44253 0.07550
