/* ** ** 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 55627.143422 0.000454 0.09745 0.01866 0.96178 0 11.54944 0.66781 4.08645 0.23627 1.12544 0.20548 0.39801 0.07267 55627.144605 0.000729 0.10380 0.01578 0.94841 0 11.09414 0.51064 3.96459 0.18247 1.15158 0.16682 0.41029 0.05943 55627.145870 0.000530 0.14885 0.02256 0.96721 0 10.74771 0.58534 3.80454 0.20718 1.59984 0.22626 0.56591 0.08003 55627.146850 0.000451 0.15141 0.02340 0.97436 0 12.06152 0.67633 4.28623 0.24034 1.82628 0.26297 0.64859 0.09339 55627.147866 0.000564 0.13118 0.02009 0.97949 0 11.06879 0.57546 3.93583 0.20460 1.45202 0.20913 0.51615 0.07432 55627.149000 0.000570 0.12269 0.01848 0.95939 0 12.08124 0.59580 4.29179 0.21167 1.48225 0.21089 0.52719 0.07500 55627.150051 0.000480 0.15089 0.02303 0.95181 0 11.72796 0.64713 4.18023 0.23065 1.76962 0.25179 0.63063 0.08972 55627.151043 0.000512 0.13366 0.02035 0.95480 0 12.25031 0.63676 4.38760 0.22806 1.63737 0.23435 0.58646 0.08394 55627.152206 0.000651 0.10143 0.01515 0.97333 0 12.64162 0.57575 4.48473 0.20425 1.28228 0.18246 0.45498 0.06473 55627.153511 0.000654 0.11650 0.01692 0.96018 0 11.72009 0.54396 4.22508 0.19609 1.36534 0.18785 0.49367 0.06793
