/* ** ** 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 55293.343186 0.000671 0.21289 0.01713 0.96983 0 21.51732 0.71460 8.16155 0.26880 4.58079 0.33584 1.74826 0.12698 55293.344589 0.000732 0.21931 0.01730 0.97628 0 21.17190 0.71008 7.34349 0.24629 4.64330 0.33156 1.60957 0.11493 55293.346062 0.000741 0.20890 0.01655 0.97656 0 21.82002 0.71618 7.55477 0.24796 4.55829 0.32870 1.57784 0.11378 55293.347546 0.000744 0.19355 0.01541 0.96887 0 23.32071 0.73761 8.09839 0.25613 4.51379 0.32980 1.56755 0.11454 55293.348900 0.000611 0.24586 0.01981 0.97630 0 22.43185 0.79610 7.76561 0.27558 5.51512 0.39904 1.90983 0.13817 55293.350217 0.000700 0.22661 0.01807 0.96281 0 21.48924 0.73127 7.47336 0.25431 4.86968 0.35115 1.69296 0.12208 55293.351533 0.000616 0.25513 0.02052 0.96714 0 21.71009 0.78169 7.54802 0.27176 5.53881 0.39838 1.92458 0.13842 55293.352821 0.000671 0.22866 0.01840 0.97414 0 21.98217 0.76109 7.61277 0.26358 5.02641 0.36509 1.74053 0.12642 55293.354508 0.001016 0.22405 0.01530 0.97151 0 20.91649 0.60090 7.25316 0.20836 4.68626 0.29043 1.62522 0.10071
