/* ** ** 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 59309.179642 0.000535 0.13291 0.01006 0.98378 0 18.80193 0.48566 16.53222 0.42698 2.49893 0.17772 2.19886 0.15635 59309.180744 0.000567 0.12356 0.00944 0.98469 0 18.65730 0.46894 16.54739 0.41588 2.30528 0.16639 2.04390 0.14750 59309.181821 0.000509 0.13431 0.01027 0.98864 0 19.04447 0.49750 16.93496 0.44238 2.55779 0.18388 2.27420 0.16345 59309.182859 0.000530 0.13060 0.00991 0.98361 0 19.06010 0.48903 16.97085 0.43542 2.48919 0.17771 2.21641 0.15824 59309.183832 0.000443 0.15434 0.01201 0.98693 0 18.98632 0.53321 16.90609 0.47479 2.93036 0.21264 2.60926 0.18934 59309.184778 0.000503 0.13305 0.01021 0.99425 0 19.48396 0.50717 17.29896 0.45026 2.59228 0.18712 2.30061 0.16607 59309.185799 0.000518 0.13610 0.01040 0.97765 0 18.78776 0.49054 16.73158 0.43686 2.55697 0.18357 2.27702 0.16347 59309.186699 0.000382 0.19575 0.01542 0.97727 0 17.53979 0.55334 15.62123 0.49282 3.43344 0.24777 3.05793 0.22067 59309.187978 0.000897 0.15306 0.00850 0.98065 0 18.47600 0.36929 16.42754 0.32834 2.82786 0.14650 2.51362 0.13021
