/* ** ** 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 57732.481030 0.000417 0.04972 0.01140 0.98611 0 6.29880 0.31680 5.67904 0.28564 0.31316 0.07003 0.28216 0.06309 57732.482066 0.000619 0.09045 0.01371 0.98598 0 5.68414 0.24768 5.13468 0.22373 0.51411 0.07463 0.46491 0.06749 57732.483224 0.000538 0.09081 0.01329 0.98387 0 6.85512 0.29094 6.15305 0.26114 0.62249 0.08717 0.55831 0.07818 57732.484395 0.000634 0.08304 0.01254 0.98174 0 6.10729 0.25461 5.50089 0.22928 0.50717 0.07362 0.45626 0.06624 57732.485617 0.000587 0.09114 0.01381 0.97537 0 6.09407 0.26507 5.44082 0.23663 0.55540 0.08061 0.49543 0.07193 57732.486733 0.000530 0.10756 0.01664 0.99454 0 5.53614 0.26542 4.96116 0.23786 0.59546 0.08759 0.53329 0.07846 57732.487575 0.000312 0.06719 0.01562 0.98148 0 6.38224 0.36875 5.78150 0.33398 0.42884 0.09653 0.38712 0.08716 57732.488186 0.000298 0.06990 0.01618 0.98058 0 6.26300 0.37342 5.66328 0.33757 0.43781 0.09790 0.39670 0.08870 57732.488808 0.000324 0.07599 0.01772 0.94643 0 5.60571 0.33962 5.09457 0.30866 0.42595 0.09590 0.38712 0.08716 57732.489662 0.000530 0.10290 0.01528 0.97268 0 6.01750 0.27209 5.46877 0.24728 0.61920 0.08757 0.56273 0.07958 57732.490926 0.000735 0.08685 0.01181 0.97244 0 6.13821 0.23430 5.55470 0.21202 0.53311 0.06958 0.48245 0.06296
