/* ** ** 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 56037.288260 0.000663 0.11343 0.00871 0.98690 0 17.01038 0.40885 15.35600 0.36903 1.92946 0.14065 1.74163 0.12695 56037.289620 0.000697 0.12001 0.00921 0.97925 0 15.38133 0.38182 13.88384 0.34464 1.84584 0.13398 1.66702 0.12103 56037.291035 0.000718 0.11386 0.00866 0.98387 0 15.90899 0.38372 14.21724 0.34290 1.81135 0.13066 1.61979 0.11682 56037.292464 0.000712 0.11803 0.00883 0.98374 0 15.54081 0.37987 14.01752 0.34261 1.83434 0.12971 1.65565 0.11707 56037.293862 0.000686 0.11877 0.00917 0.99156 0 15.63067 0.38898 14.02417 0.34897 1.85645 0.13572 1.66640 0.12179 56037.295256 0.000709 0.11344 0.00858 0.98367 0 16.18904 0.38977 14.51090 0.34935 1.83641 0.13161 1.64748 0.11804 56037.296654 0.000689 0.12089 0.00922 0.97899 0 15.50214 0.38302 14.03382 0.34674 1.87409 0.13515 1.69627 0.12234 56037.298659 0.001317 0.10983 0.00638 0.98681 0 15.24312 0.27514 13.81344 0.24932 1.67413 0.09244 1.51552 0.08368
