/* ** ** 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 56046.650556 0.000602 0.12592 0.00958 0.98558 0 17.66881 0.44610 15.33484 0.38715 2.22485 0.15976 1.93128 0.13869 56046.651632 0.000475 0.17406 0.01351 0.96951 0 16.81681 0.49768 14.38725 0.42574 2.92718 0.20999 2.50774 0.17985 56046.652607 0.000501 0.15501 0.01188 0.98844 0 17.29224 0.48363 15.06587 0.42134 2.68055 0.19128 2.33395 0.16653 56046.653614 0.000506 0.16162 0.01254 0.97714 0 16.38367 0.46964 14.27858 0.40930 2.64795 0.19088 2.30833 0.16641 56046.654697 0.000576 0.12946 0.00991 0.98995 0 17.69673 0.45511 15.47757 0.39804 2.29100 0.16516 2.00368 0.14445 56046.655912 0.000639 0.11954 0.00905 0.98190 0 17.53793 0.42982 15.33955 0.37594 2.09653 0.15017 1.83372 0.13134 56046.657101 0.000550 0.13618 0.01061 0.98947 0 17.55282 0.46668 15.24409 0.40526 2.39031 0.17501 2.07431 0.15189 56046.658195 0.000544 0.13650 0.01044 0.96809 0 18.51349 0.48251 15.97456 0.41630 2.52714 0.18171 2.17982 0.15674 56046.659922 0.001183 0.13209 0.00725 0.97555 0 16.98659 0.31232 14.76752 0.27151 2.24379 0.11602 1.95066 0.10087
