/* ** ** 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 55568.444524 0.000292 0.09478 0.01439 1.00000 0 11.10199 0.49239 10.28635 0.45615 1.05224 0.15275 0.97388 0.14139 55568.445192 0.000376 0.07321 0.01100 0.99231 0 11.30832 0.43745 10.40646 0.40252 0.82786 0.12017 0.76250 0.11070 55568.445959 0.000391 0.07458 0.01094 0.98519 0 10.87996 0.42650 10.09875 0.39588 0.81140 0.11475 0.75313 0.10651 55568.446702 0.000353 0.07501 0.01128 0.99180 0 11.67706 0.45997 10.83781 0.42691 0.87586 0.12716 0.81291 0.11802 55568.447437 0.000382 0.07751 0.01168 0.98485 0 10.51679 0.42346 9.76115 0.39304 0.81521 0.11835 0.75663 0.10985 55568.448233 0.000414 0.06578 0.01011 0.97902 0 11.29631 0.42006 10.48494 0.38989 0.74307 0.11077 0.68970 0.10281 55568.448959 0.000312 0.09661 0.01417 0.95370 0 11.06269 0.48424 10.26787 0.44945 1.06872 0.14965 0.99194 0.13890 55568.449587 0.000315 0.08701 0.01284 0.98165 0 11.59098 0.48834 10.75852 0.45327 1.00857 0.14263 0.93614 0.13239 55568.450290 0.000388 0.06772 0.01069 0.99254 0 11.33382 0.43617 10.51962 0.40484 0.76758 0.11751 0.71243 0.10907 55568.451046 0.000367 0.07792 0.01122 0.97638 0 11.61582 0.45222 10.78132 0.41974 0.90513 0.12552 0.84011 0.11650 55568.451760 0.000347 0.08366 0.01232 0.97500 0 11.02533 0.45281 10.23374 0.42030 0.92235 0.13044 0.85613 0.12107 55568.452495 0.000388 0.07022 0.01055 1.00000 0 11.26230 0.43275 10.45339 0.40167 0.79085 0.11481 0.73405 0.10657 55568.453222 0.000339 0.07862 0.01173 1.00000 0 11.75531 0.47272 10.91117 0.43877 0.92420 0.13278 0.85783 0.12325 55568.453954 0.000394 0.07952 0.01146 0.98529 0 10.53213 0.41458 9.77619 0.38482 0.83753 0.11614 0.77741 0.10781 55568.454700 0.000353 0.08146 0.01227 0.95082 0 11.21408 0.45149 10.40899 0.41907 0.91353 0.13263 0.84795 0.12310 55568.455426 0.000373 0.07510 0.01102 0.99225 0 11.29411 0.44081 10.43293 0.40719 0.84818 0.11995 0.78255 0.11067 55568.456190 0.000391 0.07013 0.01052 0.97778 0 11.44686 0.43299 10.62508 0.40190 0.80279 0.11655 0.74517 0.10818 55568.457108 0.000527 0.07719 0.00972 0.96703 0 10.80342 0.36775 10.02771 0.34135 0.83390 0.10112 0.77402 0.09386
