/* ** ** 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 58650.012356 0.000486 0.15289 0.01172 0.96429 0 19.82098 0.54285 16.07913 0.44031 3.03042 0.21690 2.45768 0.17588 58650.013285 0.000443 0.16229 0.01241 0.99346 0 19.82493 0.56807 16.31676 0.46753 3.21742 0.22803 2.64744 0.18762 58650.014112 0.000385 0.17434 0.01348 1.00000 0 20.95293 0.62859 17.16508 0.51497 3.65304 0.26020 2.99552 0.21336 58650.014960 0.000463 0.15274 0.01160 0.98125 0 20.21672 0.55926 16.69621 0.46186 3.08791 0.21835 2.55202 0.18046 58650.015854 0.000431 0.16097 0.01228 0.98658 0 20.56954 0.58567 16.98022 0.48346 3.31102 0.23442 2.73156 0.19337 58650.016731 0.000446 0.14947 0.01161 0.99351 0 21.03259 0.58497 17.19214 0.47812 3.14368 0.22804 2.56697 0.18620 58650.017567 0.000391 0.16818 0.01326 0.99259 0 20.92367 0.61977 17.31448 0.51284 3.51886 0.25712 2.91405 0.21294 58650.018343 0.000385 0.18223 0.01421 0.98496 0 20.26906 0.61587 16.64176 0.50559 3.69354 0.26532 3.03063 0.21767 58650.019153 0.000425 0.16274 0.01273 0.99320 0 20.19482 0.58650 16.57985 0.48148 3.28651 0.23869 2.69601 0.19577 58650.020009 0.000431 0.16535 0.01289 0.98658 0 19.59473 0.57295 16.19575 0.47355 3.23998 0.23418 2.67944 0.19365 58650.020822 0.000382 0.17801 0.01401 1.00000 0 20.08234 0.61307 16.71498 0.51027 3.57487 0.25932 2.97535 0.21583 58650.021606 0.000402 0.17535 0.01370 0.98561 0 19.83932 0.59787 16.48079 0.49666 3.47884 0.25077 2.88964 0.20830 58650.022807 0.000799 0.16517 0.00949 0.97464 0 19.60730 0.41843 16.27544 0.34732 3.23847 0.17278 2.68690 0.14335
