/* ** ** 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 59215.100757 0.000463 0.19610 0.01528 1.00000 0 16.53544 0.52472 12.89219 0.40819 3.24255 0.23069 2.50526 0.17788 59215.101639 0.000420 0.21403 0.01718 0.99310 0 17.48900 0.58503 12.74531 0.42627 3.74309 0.27306 2.73283 0.19927 59215.102606 0.000547 0.16032 0.01282 0.99471 0 17.83621 0.52181 12.88416 0.37690 2.85954 0.21277 2.06405 0.15356 59215.103618 0.000466 0.19745 0.01562 1.00000 0 17.11483 0.55480 12.42186 0.40262 3.37928 0.24382 2.45454 0.17707 59215.104570 0.000486 0.18341 0.01454 0.98810 0 17.94608 0.55861 12.92398 0.40227 3.29150 0.24003 2.37065 0.17286 59215.105574 0.000518 0.16942 0.01355 0.99441 0 17.87442 0.53707 12.84999 0.38606 3.02830 0.22444 2.17903 0.16147 59215.106535 0.000443 0.19586 0.01561 1.00000 0 18.19655 0.58626 13.12261 0.42275 3.56405 0.25985 2.57208 0.18755 59215.107412 0.000434 0.20421 0.01643 0.99333 0 17.82751 0.58725 12.86579 0.42378 3.64057 0.26724 2.62885 0.19297 59215.108309 0.000463 0.18432 0.01455 0.99375 0 18.71387 0.58035 13.42246 0.41626 3.44930 0.25048 2.47392 0.17966 59215.109368 0.000596 0.15693 0.01193 0.98544 0 17.59591 0.49734 12.64722 0.35744 2.76138 0.19478 1.98360 0.13991 59215.110881 0.000917 0.18848 0.01063 0.98738 0 18.02411 0.40528 12.89412 0.28993 3.39726 0.17565 2.42744 0.12550
