/* ** ** 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 58500.135583 0.000298 0.23111 0.01836 0.98058 0 19.24842 0.65852 17.01962 0.58219 4.44858 0.31887 3.93081 0.28167 58500.136240 0.000359 0.17821 0.01387 1.00000 0 20.16528 0.61271 17.98199 0.54629 3.59367 0.25753 3.20170 0.22943 58500.136957 0.000359 0.18013 0.01450 1.00000 0 19.44810 0.59935 17.37365 0.53542 3.50322 0.26061 3.12942 0.23281 58500.137666 0.000350 0.18305 0.01462 1.00000 0 19.60217 0.60880 17.59389 0.54643 3.58823 0.26410 3.22066 0.23705 58500.138349 0.000333 0.19623 0.01563 0.99130 0 19.62476 0.62874 17.59775 0.56380 3.85106 0.28079 3.45203 0.25171 58500.139014 0.000333 0.19199 0.01530 0.98261 0 20.31147 0.63815 18.13482 0.56975 3.89964 0.28549 3.48413 0.25507 58500.139686 0.000339 0.19801 0.01551 1.00000 0 19.18803 0.61552 17.22375 0.55251 3.79935 0.27156 3.41038 0.24376 58500.140348 0.000318 0.20866 0.01635 0.99091 0 19.64320 0.63866 17.63188 0.57327 4.09871 0.29221 3.67906 0.26229 58500.141060 0.000394 0.16792 0.01305 0.97794 0 19.89874 0.58341 17.79021 0.52160 3.34134 0.24039 2.98637 0.21487 58500.141778 0.000324 0.20420 0.01607 1.00000 0 19.53286 0.63568 17.37963 0.56562 3.98853 0.28584 3.54474 0.25401 58500.142432 0.000330 0.19964 0.01576 1.00000 0 19.59608 0.63086 17.55691 0.56523 3.91220 0.28188 3.50321 0.25242 58500.143112 0.000350 0.17887 0.01418 0.99174 0 20.31605 0.62340 18.23998 0.55970 3.63403 0.26569 3.26273 0.23854 58500.143797 0.000336 0.19381 0.01520 0.99138 0 20.08483 0.63478 17.91507 0.56618 3.89263 0.27933 3.47122 0.24911 58500.144434 0.000301 0.21516 0.01700 1.00000 0 20.07162 0.67440 17.82729 0.59885 4.31871 0.30873 3.83668 0.27423 58500.145059 0.000324 0.22144 0.01751 0.99107 0 18.23307 0.61700 16.25051 0.54989 4.03759 0.28859 3.59473 0.25693 58500.145681 0.000298 0.22133 0.01783 1.00000 0 19.43315 0.66538 17.25056 0.59068 4.30113 0.31373 3.82069 0.27859 58500.146587 0.000608 0.19777 0.01157 0.99524 0 19.80310 0.46968 17.52802 0.41572 3.91646 0.20946 3.46618 0.18533
