/* ** ** 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 59017.927850 0.000509 0.26240 0.00942 1.00000 0 47.54606 0.77824 43.09605 0.70536 12.47630 0.39878 11.31424 0.36161 59017.928510 0.000150 0.23414 0.01663 1.00000 0 45.71889 1.41906 41.63166 1.29217 10.70463 0.68365 9.75284 0.62283 59017.928779 0.000119 0.22917 0.01812 1.00000 0 48.07312 1.65523 42.82498 1.47453 11.01705 0.78399 9.81742 0.69864 59017.929398 0.000501 0.26740 0.00961 1.00000 0 48.07045 0.79676 43.14049 0.71499 12.85425 0.41007 11.52648 0.36770 59017.930405 0.000506 0.27250 0.00985 1.00000 0 45.79117 0.76760 41.73063 0.69951 12.47832 0.39953 11.37800 0.36429 59017.931432 0.000521 0.26132 0.00949 1.00000 0 46.10308 0.75966 41.88734 0.69013 12.04784 0.39004 10.93692 0.35405 59017.932439 0.000486 0.27416 0.00990 1.00000 0 48.13384 0.80716 43.16246 0.72378 13.19659 0.42182 11.83743 0.37836 59017.933455 0.000530 0.26246 0.00953 1.00000 0 45.14381 0.74373 41.04283 0.67614 11.84858 0.38337 10.76858 0.34842 59017.934511 0.000527 0.25791 0.00932 1.00000 0 46.74490 0.76392 42.12860 0.68840 12.05613 0.38845 10.86925 0.35018 59017.935547 0.000509 0.27045 0.00977 1.00000 0 46.25542 0.76961 41.78197 0.69514 12.50987 0.40097 11.29059 0.36187 59017.936583 0.000527 0.25265 0.00909 1.00000 0 47.71006 0.77038 43.01663 0.69457 12.05387 0.38769 10.87010 0.34958 59017.937633 0.000524 0.27457 0.00965 1.00000 0 46.79954 0.76596 42.09129 0.68888 12.84954 0.39974 11.55256 0.35939
