/* ** ** 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 58814.947814 0.000388 0.14646 0.01122 0.99254 0 23.09428 0.63276 20.46074 0.56057 3.38235 0.24188 2.99975 0.21446 58814.948615 0.000414 0.13613 0.01049 0.99301 0 22.89810 0.61070 20.55912 0.54833 3.11719 0.22530 2.79765 0.20220 58814.949451 0.000422 0.13388 0.01023 0.97945 0 23.16252 0.60536 20.84802 0.54486 3.10111 0.22262 2.79103 0.20037 58814.950291 0.000417 0.13730 0.01064 1.00000 0 22.06262 0.59426 19.89065 0.53576 3.02911 0.22008 2.73097 0.19842 58814.951283 0.000576 0.09732 0.00732 0.98995 0 23.08810 0.51621 20.81743 0.46544 2.24688 0.16130 2.02598 0.14545 58814.952278 0.000420 0.12970 0.00989 1.00000 0 23.41213 0.60701 21.10854 0.54728 3.03644 0.21764 2.73768 0.19622 58814.953123 0.000425 0.13571 0.01044 0.97959 0 22.54226 0.59298 20.32956 0.53478 3.05912 0.22110 2.75879 0.19939 58814.954041 0.000492 0.11015 0.00831 0.98235 0 23.92492 0.56566 21.57865 0.51019 2.63535 0.18889 2.37702 0.17037 58814.954943 0.000411 0.13130 0.01034 1.00000 0 23.03428 0.60973 20.79472 0.55045 3.02439 0.22429 2.73031 0.20248 58814.955817 0.000463 0.11753 0.00905 0.98750 0 23.47607 0.57824 21.18541 0.52182 2.75916 0.20130 2.48994 0.18166 58814.956717 0.000437 0.12730 0.01007 0.98013 0 22.69926 0.59065 20.48069 0.53292 2.88951 0.21576 2.60711 0.19467 58814.957724 0.000570 0.11736 0.00815 0.98985 0 23.10816 0.51684 20.85936 0.46655 2.71206 0.17829 2.44820 0.16094
