/* ** ** 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 58457.572261 0.000376 0.23262 0.01961 1.00000 0 31.24610 1.13627 12.59840 0.45665 7.26835 0.55294 2.93943 0.22255 58457.573030 0.000394 0.26590 0.02198 0.99265 0 29.88710 1.13129 10.88574 0.41204 7.94690 0.58401 2.90034 0.21306 58457.573875 0.000451 0.22736 0.01889 0.99359 0 29.83437 1.05598 10.90863 0.38604 6.78316 0.50999 2.47729 0.18627 58457.574764 0.000437 0.25312 0.02084 0.99338 0 28.55390 1.06208 10.31059 0.38350 7.22767 0.53097 2.61031 0.19175 58457.575623 0.000422 0.26059 0.02158 0.99315 0 28.46951 1.07677 10.30800 0.38980 7.41878 0.54642 2.68650 0.19788 58457.576529 0.000483 0.24969 0.02003 0.96407 0 28.35143 1.01954 9.87277 0.35506 7.07911 0.50771 2.46849 0.17701 58457.577489 0.000477 0.25376 0.02044 0.97576 0 27.94163 1.01238 9.69929 0.35139 7.09038 0.51010 2.46198 0.17713 58457.578435 0.000469 0.23728 0.01888 0.96914 0 30.19338 1.04906 10.72008 0.37243 7.16416 0.51282 2.54569 0.18211 58457.579384 0.000480 0.22585 0.01861 0.98193 0 29.02210 1.02292 10.53652 0.37137 6.55453 0.48828 2.37933 0.17719 58457.580281 0.000417 0.25424 0.02114 0.97222 0 30.11513 1.10171 10.83078 0.39621 7.65661 0.57186 2.75591 0.20581 58457.581138 0.000440 0.24565 0.02103 0.97368 0 28.94858 1.07604 10.41126 0.38696 7.11114 0.54830 2.55782 0.19716 58457.582110 0.000532 0.23097 0.01800 0.98913 0 29.36231 0.97204 10.57905 0.35021 6.78178 0.47837 2.44322 0.17234
