/* ** ** 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 55594.284767 0.000469 0.12420 0.02421 0.96296 0 6.48030 0.42490 3.15717 0.20298 0.80485 0.14771 0.39810 0.07150 55594.285586 0.000350 0.11210 0.02681 0.94215 0 7.03122 0.52946 3.11055 0.23411 0.78822 0.17893 0.34685 0.07872 55594.286529 0.000593 0.14378 0.02464 0.95610 0 6.08074 0.37094 2.76545 0.16869 0.87430 0.14001 0.39862 0.06383 55594.287661 0.000538 0.07599 0.01762 0.96237 0 6.49626 0.39980 2.95067 0.18160 0.49363 0.11038 0.22384 0.05005 55594.288714 0.000515 0.08358 0.01947 0.98876 0 5.98264 0.39083 2.71573 0.17740 0.50006 0.11182 0.22765 0.05090 55594.289961 0.000732 0.05201 0.01210 0.97233 0 6.79577 0.34860 3.11051 0.15953 0.35346 0.08020 0.16073 0.03648 55594.291301 0.000608 0.06372 0.01456 0.99048 0 6.94373 0.39439 3.12933 0.17773 0.44247 0.09795 0.19973 0.04421 55594.292484 0.000576 0.06947 0.01609 0.97990 0 6.57978 0.39662 2.95517 0.17812 0.45709 0.10223 0.20547 0.04594 55594.293474 0.000414 0.10454 0.02497 0.98601 0 5.87546 0.43573 2.67347 0.19824 0.61422 0.13945 0.28043 0.06365 55594.294498 0.000611 0.08969 0.01803 0.95735 0 6.54967 0.38072 2.99049 0.17382 0.58741 0.11305 0.26777 0.05153
