/* ** ** 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 58108.172878 0.000420 0.26449 0.00959 0.99310 0 56.78502 0.93471 51.92908 0.85474 15.01916 0.48552 13.73421 0.44391 58108.173731 0.000434 0.25662 0.00942 1.00000 0 54.51718 0.89499 51.01768 0.83754 13.98999 0.45920 13.09214 0.42972 58108.174588 0.000422 0.27223 0.01003 1.00000 0 53.59191 0.90588 49.52369 0.83703 14.58933 0.47755 13.48403 0.44128 58108.175441 0.000431 0.26360 0.00956 1.00000 0 53.84684 0.89359 50.37643 0.83600 14.19377 0.45789 13.27898 0.42838 58108.176269 0.000396 0.28428 0.01038 1.00000 0 55.57888 0.95437 50.96118 0.87498 15.79971 0.50897 14.48597 0.46659 58108.177105 0.000440 0.25583 0.00928 1.00000 0 55.61820 0.90563 50.98780 0.83016 14.22881 0.46096 13.03982 0.42241 58108.178364 0.000819 0.26373 0.00701 0.99793 0 54.16632 0.65732 49.67843 0.60283 14.28532 0.33790 13.10499 0.30996 58108.422926 0.000451 0.25359 0.00914 1.00000 0 54.28097 0.88141 50.26601 0.81616 13.76485 0.44306 12.73563 0.40991 58108.423852 0.000475 0.23874 0.00861 1.00000 0 54.25550 0.85218 50.55816 0.79411 12.95269 0.42047 12.06996 0.39181 58108.424789 0.000463 0.23718 0.00861 1.00000 0 55.72543 0.87733 51.75904 0.81486 13.21669 0.43222 12.27382 0.40141 58108.425736 0.000483 0.23249 0.00843 1.00000 0 54.42503 0.84545 50.69933 0.78756 12.65326 0.41470 11.78552 0.38626 58108.426977 0.000758 0.26090 0.00723 1.00000 0 53.38598 0.67431 49.74871 0.62837 13.92818 0.34343 12.97925 0.32003
