/* ** ** 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 57430.175098 0.000365 0.10438 0.01591 0.99206 0 8.81705 0.41221 7.51609 0.35133 0.92032 0.13354 0.78487 0.11392 57430.175819 0.000356 0.09969 0.01498 0.99187 0 9.41678 0.42834 8.14908 0.37065 0.93873 0.13447 0.81260 0.11642 57430.176658 0.000483 0.07628 0.01149 0.99401 0 9.02272 0.36154 7.74819 0.31046 0.68827 0.09990 0.59101 0.08578 57430.177671 0.000530 0.07081 0.01049 0.97268 0 9.16657 0.34685 7.85621 0.29725 0.64909 0.09299 0.55695 0.07979 57430.178663 0.000463 0.08218 0.01226 0.96875 0 9.13040 0.36920 7.85937 0.31781 0.75036 0.10779 0.64588 0.09278 57430.179641 0.000515 0.07115 0.01068 0.98876 0 9.10116 0.35063 7.83394 0.30180 0.64753 0.09399 0.55743 0.08091 57430.180506 0.000350 0.11101 0.01699 0.97521 0 8.83282 0.42007 7.55938 0.35949 0.98055 0.14266 0.83968 0.12218 57430.181154 0.000298 0.12984 0.02001 0.98058 0 8.69087 0.45076 7.47981 0.38795 1.12842 0.16378 0.97137 0.14099 57430.181846 0.000394 0.09927 0.01490 0.97059 0 8.78859 0.39397 7.56489 0.33912 0.87248 0.12500 0.75104 0.10760 57430.182749 0.000509 0.07687 0.01117 0.97159 0 9.03632 0.35080 7.76979 0.30164 0.69463 0.09727 0.59749 0.08366 57430.183967 0.000709 0.07274 0.00923 0.98776 0 8.93593 0.29617 7.68040 0.25456 0.64997 0.07957 0.55867 0.06840
