/* ** ** 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 56616.799845 0.000425 0.20546 0.01632 1.00000 0 14.26350 0.46606 13.10357 0.42818 2.93058 0.21217 2.69023 0.19476 56616.800878 0.000608 0.14602 0.01127 0.99524 0 14.06908 0.38492 13.03038 0.35651 2.05441 0.14833 1.90175 0.13732 56616.801986 0.000501 0.17080 0.01313 0.98844 0 14.89929 0.43962 13.72996 0.40508 2.54478 0.18066 2.34426 0.16643 56616.802938 0.000451 0.19032 0.01483 0.98077 0 14.76920 0.45863 13.70551 0.42560 2.81092 0.20086 2.60828 0.18638 56616.803930 0.000541 0.15656 0.01227 0.97861 0 14.99500 0.42705 13.69284 0.38992 2.34759 0.17148 2.14021 0.15637 56616.804992 0.000521 0.15637 0.01234 0.98333 0 15.29447 0.43586 14.09844 0.40178 2.39162 0.17592 2.20258 0.16199 56616.806329 0.000816 0.16944 0.01032 0.99059 0 14.86435 0.34233 13.73604 0.31635 2.51862 0.14200 2.32791 0.13123 56616.846824 0.000498 0.16165 0.01252 0.98837 0 16.20983 0.46525 14.44404 0.41457 2.62039 0.18855 2.33622 0.16812 56616.847770 0.000448 0.17625 0.01370 0.98065 0 16.73729 0.50501 14.81670 0.44709 2.94998 0.21140 2.61179 0.18717 56616.848720 0.000501 0.15903 0.01235 0.98844 0 16.28207 0.46710 14.53085 0.41687 2.58936 0.18682 2.31084 0.16672 56616.849677 0.000457 0.19637 0.01522 0.98734 0 15.30818 0.47556 13.63509 0.42358 3.00604 0.21338 2.67749 0.19006
