/* ** ** 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 59168.170415 0.000307 0.16841 0.01334 1.00000 0 32.28190 0.96488 22.15431 0.65627 5.43660 0.39883 3.71269 0.26938 59168.170982 0.000260 0.19156 0.01503 1.00000 0 32.96880 1.04536 22.92457 0.72600 6.31543 0.45339 4.41228 0.31603 59168.171576 0.000333 0.19586 0.01551 1.00000 0 28.92153 0.92619 17.54774 0.56181 5.66471 0.41014 3.43955 0.24891 59168.172209 0.000301 0.23085 0.01824 0.99038 0 27.70026 0.96091 16.85226 0.58459 6.39465 0.45396 3.89213 0.27629 59168.172855 0.000344 0.18312 0.01451 0.99160 0 29.74585 0.92772 18.21870 0.56820 5.44719 0.39677 3.33701 0.24305 59168.173563 0.000365 0.17413 0.01383 1.00000 0 29.14938 0.88995 17.86800 0.54550 5.07591 0.37212 3.11101 0.22806 59168.174238 0.000310 0.19964 0.01568 0.99065 0 30.55990 0.98370 18.76501 0.60402 6.10083 0.43696 3.74628 0.26833 59168.174877 0.000330 0.19199 0.01549 0.98246 0 29.67759 0.93727 18.06745 0.57060 5.69785 0.42306 3.46809 0.25755 59168.175554 0.000347 0.17183 0.01368 1.00000 0 31.02507 0.94010 19.01661 0.57623 5.33098 0.39236 3.26842 0.24050 59168.176474 0.000573 0.16869 0.01056 0.98022 0 30.50963 0.72234 18.80457 0.44516 5.14654 0.29825 3.17574 0.18399
