/* ** ** 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 57414.090368 0.000544 0.13750 0.01070 0.98936 0 17.21464 0.46010 15.31283 0.40928 2.36704 0.17303 2.10519 0.15388 57414.091471 0.000558 0.13941 0.01076 0.98964 0 16.76513 0.44870 14.85245 0.39748 2.33723 0.16925 2.07010 0.14992 57414.092567 0.000538 0.14287 0.01111 0.99462 0 16.88509 0.45850 14.88970 0.40432 2.41231 0.17582 2.12740 0.15509 57414.093667 0.000561 0.13383 0.01014 0.98969 0 17.60792 0.45829 15.53982 0.40441 2.35655 0.16774 2.07733 0.14786 57414.094758 0.000524 0.15292 0.01174 0.97238 0 16.75551 0.46306 14.75693 0.40781 2.56222 0.18359 2.25583 0.16164 57414.095825 0.000544 0.14275 0.01118 0.99468 0 16.52410 0.45191 14.68570 0.40163 2.35876 0.17311 2.09491 0.15374 57414.096974 0.000605 0.12686 0.00965 0.99522 0 17.14931 0.43765 15.06886 0.38454 2.17564 0.15590 1.90878 0.13677 57414.098143 0.000564 0.13914 0.01071 0.98974 0 16.52636 0.44411 14.71720 0.39549 2.29941 0.16586 2.04770 0.14770 57414.099700 0.000992 0.13702 0.00798 0.97668 0 17.19228 0.34104 15.22479 0.30200 2.35566 0.12892 2.08599 0.11416
