/* ** ** 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 60025.057228 0.000561 0.12373 0.00932 0.98454 0 18.61849 0.46311 16.99714 0.42278 2.30358 0.16381 2.10248 0.14951 60025.058351 0.000561 0.12260 0.00933 0.98454 0 18.41169 0.45977 16.91208 0.42232 2.25723 0.16221 2.07339 0.14900 60025.059479 0.000567 0.12009 0.00910 0.97959 0 18.79305 0.46434 17.26231 0.42652 2.25685 0.16176 2.07302 0.14859 60025.060700 0.000654 0.09955 0.00754 0.98673 0 19.34434 0.43673 17.76875 0.40116 1.92575 0.13914 1.76891 0.12781 60025.061910 0.000556 0.12126 0.00918 1.00000 0 18.59088 0.46596 17.07669 0.42800 2.25426 0.16112 2.07066 0.14800 60025.063024 0.000558 0.11360 0.00861 0.98964 0 19.86967 0.47935 18.25126 0.44031 2.25724 0.16221 2.07339 0.14900 60025.064126 0.000544 0.12823 0.00976 0.98404 0 18.26560 0.46698 16.77776 0.42894 2.34224 0.16788 2.15146 0.15421 60025.065179 0.000509 0.12945 0.00987 0.97159 0 19.47644 0.49720 17.88980 0.45670 2.52128 0.18118 2.31589 0.16642 60025.066267 0.000579 0.11752 0.00897 0.99000 0 18.45568 0.45375 16.95262 0.41680 2.16889 0.15670 1.99226 0.14394 60025.067439 0.000593 0.12449 0.00905 0.99512 0 18.50364 0.44846 16.99644 0.41193 2.30343 0.15792 2.11580 0.14506
