/* ** ** 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 58280.327175 0.000388 0.16334 0.01286 0.99254 0 20.06592 0.58703 18.03594 0.52761 3.27748 0.23947 2.94507 0.21514 58280.328005 0.000443 0.14367 0.01120 0.98693 0 20.26920 0.55188 18.04650 0.49131 2.91207 0.21270 2.59400 0.18950 58280.328827 0.000379 0.16036 0.01257 1.00000 0 21.09315 0.61015 18.72734 0.54169 3.38242 0.24639 3.00532 0.21896 58280.329640 0.000434 0.14157 0.01098 1.00000 0 21.07944 0.57213 18.63197 0.50570 2.98431 0.21686 2.63800 0.19169 58280.330496 0.000422 0.15077 0.01187 0.99315 0 20.10526 0.56654 17.83631 0.50258 3.03124 0.22291 2.68896 0.19773 58280.331315 0.000396 0.16465 0.01289 0.98540 0 20.02495 0.58856 17.70319 0.52031 3.29702 0.23928 2.91473 0.21154 58280.332143 0.000431 0.14510 0.01148 1.00000 0 20.18735 0.56307 17.94797 0.50059 2.92926 0.21690 2.60473 0.19280 58280.333028 0.000454 0.14376 0.01102 0.98726 0 19.94026 0.54337 17.80529 0.48516 2.86670 0.20533 2.56179 0.18352 58280.333940 0.000457 0.13867 0.01080 0.99367 0 20.35490 0.54764 17.98882 0.48398 2.82265 0.20620 2.49487 0.18226 58280.334848 0.000451 0.15015 0.01151 0.98718 0 19.37517 0.53650 17.26719 0.47808 2.90922 0.20790 2.59144 0.18516 58280.335664 0.000365 0.18127 0.01455 1.00000 0 19.12774 0.59321 17.00999 0.52753 3.46732 0.25668 3.08019 0.22799 58280.336448 0.000420 0.15722 0.01233 0.97931 0 19.68090 0.56234 17.54716 0.50135 3.09420 0.22606 2.75841 0.20151 58280.337314 0.000446 0.14603 0.01141 0.99351 0 19.81999 0.54782 17.53082 0.48455 2.89437 0.21144 2.56009 0.18702 58280.338315 0.000556 0.13931 0.00962 0.99479 0 20.30453 0.49417 18.12966 0.44118 2.82854 0.18282 2.52886 0.16344
