/* ** ** 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 60097.149484 0.000616 0.18701 0.01516 0.99061 0 15.31972 0.48688 9.82545 0.30997 2.86490 0.21371 1.83074 0.13550 60097.150598 0.000498 0.18170 0.01444 0.97674 0 17.54953 0.54768 12.81374 0.39984 3.18874 0.23305 2.33076 0.17037 60097.151686 0.000590 0.16835 0.01331 0.98039 0 15.86427 0.47778 11.63258 0.35028 2.67076 0.19523 1.95783 0.14311 60097.152867 0.000590 0.16416 0.01326 0.97549 0 16.14363 0.48008 11.77800 0.35021 2.65014 0.19900 1.93109 0.14499 60097.154016 0.000558 0.18335 0.01457 0.97927 0 15.35692 0.47811 11.28697 0.35133 2.81573 0.20583 2.07178 0.15144 60097.155118 0.000544 0.19258 0.01519 0.97340 0 15.44759 0.49230 11.20264 0.35707 2.97489 0.21460 2.15960 0.15577 60097.156203 0.000541 0.17729 0.01409 0.98396 0 16.31871 0.49776 11.99960 0.36588 2.89321 0.21229 2.12908 0.15625 60097.157358 0.000613 0.16680 0.01299 0.96226 0 15.94414 0.46903 11.60939 0.34152 2.65944 0.19178 1.93729 0.13974 60097.158512 0.000541 0.18625 0.01502 0.97326 0 15.78485 0.50270 11.44163 0.36426 2.93996 0.21783 2.13147 0.15790 60097.160077 0.001024 0.16334 0.00985 0.99435 0 15.96712 0.36285 11.64207 0.26454 2.60804 0.14574 1.89937 0.10611
