/* ** ** 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 59994.128561 0.000396 0.13360 0.01020 0.99270 0 24.10371 0.63610 21.82420 0.57593 3.22036 0.23081 2.91882 0.20921 59994.129310 0.000353 0.15474 0.01193 1.00000 0 23.19285 0.65716 21.02753 0.59580 3.58877 0.25722 3.25377 0.23322 59994.130080 0.000417 0.12942 0.00980 0.98611 0 24.07463 0.61846 21.72143 0.55794 3.11576 0.22184 2.80855 0.19994 59994.130910 0.000414 0.12904 0.00972 0.99301 0 24.32235 0.62471 21.94810 0.56374 3.13861 0.22232 2.83676 0.20094 59994.131822 0.000498 0.10882 0.00827 0.99419 0 23.41158 0.55798 21.23119 0.50603 2.54775 0.18385 2.31057 0.16674 59994.132693 0.000373 0.14195 0.01098 0.98450 0 24.36052 0.65978 21.93724 0.59409 3.45795 0.25051 3.11226 0.22554 59994.133459 0.000394 0.12447 0.00984 1.00000 0 25.31188 0.65455 22.78936 0.58924 3.15050 0.23528 2.83706 0.21186 59994.134252 0.000399 0.13011 0.01003 0.99275 0 24.60872 0.64391 22.15944 0.57985 3.20191 0.23208 2.88508 0.20907 59994.135088 0.000437 0.11473 0.00888 0.98675 0 25.18950 0.61672 22.90507 0.56079 2.88994 0.21229 2.62785 0.19304 59994.135962 0.000437 0.12167 0.00949 1.00000 0 23.30554 0.59628 21.20355 0.54250 2.83562 0.20887 2.57978 0.19002 59994.136934 0.000535 0.11396 0.00785 1.00000 0 25.10493 0.55659 22.82815 0.50611 2.86089 0.18663 2.60135 0.16969
