/* ** ** 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 58873.178285 0.000174 0.18396 0.01488 1.00000 0 39.94882 1.25061 34.97531 1.09479 7.34905 0.54802 6.43593 0.47987 58873.178653 0.000194 0.17634 0.01390 1.00000 0 38.19312 1.16941 33.25558 1.01806 6.73496 0.48909 5.87181 0.42631 58873.179037 0.000191 0.17672 0.01382 0.98485 0 38.70798 1.17183 34.40860 1.04167 6.84035 0.49335 6.08039 0.43854 58873.179431 0.000203 0.16391 0.01284 1.00000 0 38.77358 1.13003 34.47962 1.00489 6.35535 0.46203 5.65149 0.41086 58873.179816 0.000182 0.17972 0.01432 1.00000 0 38.90423 1.20784 34.60247 1.07429 6.99201 0.51304 6.21884 0.45631 58873.180157 0.000159 0.20968 0.01675 0.98182 0 39.28569 1.30222 34.93951 1.15816 8.23734 0.59885 7.32600 0.53260 58873.180496 0.000179 0.18234 0.01424 1.00000 0 39.71014 1.22449 35.31530 1.08897 7.24058 0.51952 6.43922 0.46202 58873.180875 0.000200 0.16876 0.01338 1.00000 0 38.04128 1.13513 33.83332 1.00956 6.42000 0.47165 5.70985 0.41947 58873.181268 0.000194 0.16615 0.01283 1.00000 0 40.30469 1.18138 35.84589 1.05069 6.69667 0.47858 5.95586 0.42564 58873.181656 0.000194 0.17357 0.01328 1.00000 0 39.34071 1.17343 34.98573 1.04353 6.82854 0.48119 6.07263 0.42792 58873.182032 0.000182 0.18573 0.01446 1.00000 0 38.74908 1.20179 34.46100 1.06879 7.19704 0.51376 6.40061 0.45691 58873.182414 0.000200 0.16404 0.01264 1.00000 0 40.05553 1.16252 35.62486 1.03393 6.57086 0.46906 5.84404 0.41718 58873.182811 0.000197 0.17368 0.01338 1.00000 0 38.16368 1.14301 33.94111 1.01655 6.62829 0.47060 5.89494 0.41853 58873.183190 0.000182 0.17038 0.01319 1.00000 0 41.79961 1.24702 37.17519 1.10906 7.12189 0.50897 6.33401 0.45266 58873.183540 0.000168 0.20372 0.01603 0.98276 0 38.65644 1.25004 34.38106 1.11179 7.87505 0.56505 7.00407 0.50255 58873.183896 0.000188 0.18019 0.01402 0.98462 0 39.12157 1.19385 34.79234 1.06174 7.04939 0.50451 6.26930 0.44868 58873.184269 0.000185 0.17388 0.01400 1.00000 0 39.43631 1.20764 35.07681 1.07414 6.85735 0.51045 6.09925 0.45402 58873.184622 0.000168 0.20400 0.01662 1.00000 0 37.09742 1.23069 32.99183 1.09448 7.56769 0.56333 6.73021 0.50099 58873.184966 0.000177 0.18539 0.01449 1.00000 0 39.47603 1.23326 35.10887 1.09682 7.31850 0.52436 6.50884 0.46635 58873.185328 0.000185 0.18838 0.01462 0.98438 0 37.78633 1.17083 33.60676 1.04133 7.11832 0.50667 6.33100 0.45063 58873.185716 0.000203 0.16451 0.01267 1.00000 0 39.15904 1.14359 34.82645 1.01706 6.44199 0.45921 5.72922 0.40840 58873.186101 0.000182 0.18328 0.01457 1.00000 0 38.13325 1.19337 33.91476 1.06135 6.98901 0.51080 6.21583 0.45429 58873.186537 0.000255 0.16633 0.01144 0.98263 0 39.68325 1.03220 35.29317 0.91801 6.60033 0.42026 5.87015 0.37377
