/* ** ** 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 56342.138930 0.000330 0.15582 0.02442 0.99123 0 8.71449 0.50372 5.46633 0.31411 1.35792 0.19782 0.86786 0.12605 56342.139627 0.000367 0.11807 0.01764 0.96063 0 10.12160 0.48764 6.97610 0.33606 1.19502 0.16904 0.82104 0.11611 56342.140428 0.000434 0.10843 0.01637 0.99333 0 9.23849 0.43930 6.11444 0.29072 1.00173 0.14356 0.66522 0.09533 56342.141244 0.000382 0.14297 0.02191 0.97727 0 7.97754 0.43351 5.34371 0.29025 1.14051 0.16343 0.76835 0.11011 56342.142011 0.000385 0.13313 0.02007 0.97744 0 8.66861 0.45296 5.78987 0.30249 1.15403 0.16321 0.77051 0.10897 56342.142824 0.000428 0.15122 0.02064 0.95270 0 9.41154 0.44819 6.23087 0.29673 1.42321 0.18204 0.94248 0.12049 56342.143632 0.000379 0.12242 0.01858 0.98473 0 9.60786 0.48101 6.26832 0.31383 1.17621 0.16856 0.76835 0.11011 56342.144329 0.000318 0.15839 0.02414 0.97273 0 8.92913 0.50745 5.90238 0.33545 1.41431 0.20002 0.93614 0.13239 56342.145252 0.000605 0.12602 0.01514 0.97711 0 9.40005 0.37569 6.28630 0.25123 1.18455 0.13426 0.79367 0.08996 56342.206417 0.001157 0.13354 0.01028 0.99000 0 14.09875 0.37278 7.42051 0.19545 1.88281 0.13608 0.99847 0.07179 56342.208630 0.001056 0.13748 0.01054 0.98082 0 15.52099 0.41152 8.04292 0.21317 2.13376 0.15354 1.10445 0.07941 56342.209999 0.000312 0.11943 0.01861 0.98148 0 14.62812 0.72977 7.65363 0.38151 1.74707 0.25796 0.91512 0.13475 56342.211052 0.000741 0.13614 0.01290 0.96484 0 14.35487 0.46887 7.61561 0.24863 1.95420 0.17391 1.03774 0.09232
