/* ** ** 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 55225.352884 0.000579 0.13337 0.01026 0.98500 0 16.97752 0.44230 15.07557 0.39272 2.26428 0.16386 2.00772 0.14531 55225.354065 0.000602 0.12710 0.00972 0.99038 0 16.76161 0.42872 15.09806 0.38616 2.13032 0.15359 1.91895 0.13835 55225.355173 0.000506 0.14678 0.01144 0.99429 0 17.10302 0.47557 15.41666 0.42868 2.51036 0.18287 2.26283 0.16484 55225.356171 0.000492 0.15970 0.01235 0.98235 0 16.52509 0.47113 14.89727 0.42472 2.63909 0.18978 2.37909 0.17108 55225.357167 0.000503 0.14867 0.01148 0.98851 0 17.15104 0.47473 15.45856 0.42788 2.54988 0.18384 2.29828 0.16570 55225.358234 0.000564 0.13417 0.01051 0.97949 0 16.88645 0.44505 15.22393 0.40124 2.26563 0.16720 2.04271 0.15075 55225.359371 0.000573 0.14063 0.01096 0.99495 0 15.68499 0.42647 14.14007 0.38446 2.20583 0.16111 1.98847 0.14524 55225.360482 0.000538 0.14641 0.01123 0.97849 0 16.52666 0.45362 14.90300 0.40905 2.41962 0.17332 2.18182 0.15629 55225.361617 0.000596 0.12956 0.01004 0.97087 0 16.76833 0.43279 15.11801 0.39020 2.17250 0.15868 1.95865 0.14306 55225.362777 0.000564 0.13126 0.01049 0.98462 0 16.84842 0.44382 15.18961 0.40012 2.21152 0.16691 1.99371 0.15047 55225.363952 0.000611 0.14025 0.01036 0.99526 0 16.34112 0.41995 14.72871 0.37851 2.29183 0.15875 2.06571 0.14309
