/* ** ** 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 59747.134821 0.000391 0.14720 0.01131 0.99259 0 21.80175 0.60013 20.09568 0.55314 3.20924 0.23014 2.95896 0.21219 59747.135599 0.000388 0.15180 0.01154 0.98507 0 21.93343 0.60669 20.13839 0.55701 3.32947 0.23584 3.05984 0.21675 59747.136386 0.000399 0.14433 0.01111 0.99275 0 21.71308 0.58993 20.11406 0.54648 3.13392 0.22568 2.90313 0.20906 59747.137202 0.000417 0.13953 0.01057 0.97917 0 22.05144 0.58211 20.42748 0.53924 3.07692 0.21851 2.85032 0.20241 59747.138030 0.000411 0.13793 0.01051 0.99296 0 22.19128 0.59045 20.46470 0.54447 3.06087 0.21847 2.82191 0.20141 59747.138805 0.000365 0.14905 0.01148 0.99206 0 23.00983 0.63814 21.31506 0.59114 3.42951 0.24645 3.17692 0.22830 59747.139520 0.000350 0.14776 0.01151 1.00000 0 23.68871 0.65949 21.94386 0.61091 3.50025 0.25458 3.24242 0.23583 59747.140298 0.000428 0.13435 0.01029 0.97297 0 22.19276 0.58110 20.55795 0.53829 2.98164 0.21472 2.76201 0.19890 59747.141207 0.000480 0.11401 0.00863 0.98193 0 23.03308 0.55619 21.33669 0.51523 2.62592 0.18831 2.43252 0.17444 59747.142066 0.000379 0.14536 0.01131 1.00000 0 22.24131 0.61518 20.60312 0.56987 3.23304 0.23514 2.99491 0.21782 59747.143102 0.000657 0.12036 0.00770 0.99509 0 22.82774 0.47174 21.14622 0.43699 2.74761 0.16645 2.54522 0.15419 59747.201575 0.000489 0.12167 0.00946 0.98817 0 20.83687 0.52475 19.19962 0.48351 2.53514 0.18638 2.33473 0.17168 59747.202521 0.000457 0.12778 0.00981 0.98101 0 21.67396 0.55531 19.96887 0.51162 2.76953 0.20044 2.55156 0.18470 59747.203473 0.000495 0.12290 0.00928 0.98830 0 21.07216 0.53070 19.20059 0.48354 2.58975 0.18430 2.36019 0.16798 59747.204752 0.000784 0.12388 0.00747 0.98893 0 21.01442 0.41948 19.15395 0.38228 2.60334 0.14803 2.37351 0.13497
