/* ** ** 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 55323.869399 0.000535 0.33790 0.01248 1.00000 0 34.51997 0.64018 31.85107 0.59066 11.66424 0.37273 10.76254 0.34391 55323.870441 0.000506 0.35034 0.01307 1.00000 0 34.88766 0.66280 32.30098 0.61366 12.22247 0.39251 11.31531 0.36337 55323.871477 0.000530 0.33088 0.01231 1.00000 0 35.24184 0.65300 32.63411 0.60468 11.66093 0.37624 10.79809 0.34840 55323.872512 0.000506 0.33564 0.01242 1.00000 0 36.53245 0.67867 33.82940 0.62846 12.26190 0.39222 11.35465 0.36320 55323.873528 0.000509 0.34522 0.01291 0.99432 0 35.28684 0.66624 32.67594 0.61694 12.18159 0.39325 11.28026 0.36415 55323.874558 0.000521 0.33141 0.01244 1.00000 0 35.47127 0.65901 32.84667 0.61025 11.75537 0.38344 10.88556 0.35507 55323.875614 0.000535 0.31292 0.01154 1.00000 0 36.87899 0.66388 34.15003 0.61475 11.54002 0.37144 10.68608 0.34396 55323.876679 0.000530 0.32458 0.01211 1.00000 0 35.74150 0.65673 33.09710 0.60814 11.60100 0.37667 10.74268 0.34880 55323.877724 0.000515 0.32871 0.01216 1.00000 0 36.54757 0.67197 33.84314 0.62225 12.01358 0.38580 11.12460 0.35725 55323.878739 0.000501 0.34247 0.01277 1.00000 0 36.11389 0.67965 33.44168 0.62936 12.36778 0.39793 11.45264 0.36848 55323.879894 0.000654 0.33827 0.01091 1.00000 0 36.90879 0.59971 34.17754 0.55533 12.48522 0.34805 11.56131 0.32229
