/* ** ** 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 59279.157550 0.000353 0.14967 0.02337 0.98361 0 13.50843 0.76816 5.46067 0.31051 2.02186 0.29406 0.81651 0.11875 59279.158247 0.000344 0.15602 0.02410 0.95798 0 13.43653 0.76739 5.53995 0.31630 2.09635 0.30085 0.86907 0.12463 59279.158942 0.000350 0.13464 0.02055 0.95041 0 15.74270 0.82382 6.39401 0.33453 2.11962 0.30392 0.86151 0.12355 59279.159616 0.000324 0.17659 0.02779 0.92857 0 13.32524 0.79990 5.32422 0.31958 2.35311 0.34230 0.94213 0.13702 59279.160267 0.000327 0.16432 0.02479 0.96460 0 14.70347 0.83675 5.91817 0.33675 2.41604 0.33761 0.97243 0.13580 59279.160907 0.000312 0.15509 0.02491 0.98148 0 14.45041 0.84639 5.82963 0.34137 2.24107 0.33520 0.90374 0.13522 59279.161540 0.000321 0.15178 0.02337 0.95495 0 15.33887 0.85843 6.16349 0.34492 2.32810 0.33389 0.93466 0.13404 59279.162365 0.000503 0.13732 0.01808 0.97406 0 14.63550 0.68245 5.87859 0.27410 2.00968 0.24750 0.80806 0.09952
