/* ** ** 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 55930.533605 0.000339 0.12832 0.02006 0.96581 0 9.99193 0.51347 6.74838 0.34570 1.28219 0.18930 0.85866 0.12638 55930.534398 0.000454 0.15932 0.01964 0.98726 0 10.62452 0.49198 6.22514 0.28737 1.69274 0.19343 0.99520 0.11341 55930.535286 0.000434 0.12968 0.01950 0.98000 0 9.75537 0.49952 5.25350 0.26900 1.26504 0.17891 0.68141 0.09637 55930.536279 0.000558 0.16657 0.01881 0.97927 0 10.92072 0.46474 5.92237 0.25203 1.81903 0.19029 0.98530 0.10307 55930.537199 0.000362 0.15147 0.02300 0.97600 0 10.09499 0.55743 5.42928 0.29984 1.52905 0.21625 0.82104 0.11611 55930.537887 0.000327 0.17313 0.02716 0.95575 0 9.72545 0.57795 5.24465 0.31164 1.68372 0.24443 0.90810 0.13188 55930.538573 0.000359 0.15491 0.02415 0.97581 0 9.61041 0.54503 5.23945 0.29713 1.48877 0.21622 0.81053 0.11771 55930.539328 0.000396 0.13609 0.02104 0.98540 0 9.92515 0.52657 5.33683 0.28314 1.35073 0.19619 0.72648 0.10550 55930.540069 0.000344 0.15686 0.02444 0.96639 0 10.05813 0.56691 5.43863 0.30649 1.57774 0.22921 0.85282 0.12385 55930.540729 0.000315 0.18313 0.02773 0.98165 0 9.96283 0.59657 5.37394 0.32179 1.82448 0.25376 0.98253 0.13665 55930.541365 0.000321 0.14887 0.02316 0.98198 0 11.19261 0.62491 6.05350 0.33794 1.66628 0.24190 0.89977 0.13067 55930.542016 0.000330 0.15185 0.02306 0.96491 0 11.12535 0.61597 6.01543 0.33301 1.68934 0.23893 0.91061 0.12878 55930.543038 0.000692 0.14985 0.01638 0.99163 0 10.19953 0.40511 5.51524 0.21905 1.52837 0.15567 0.82801 0.08434
