/* ** ** 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 59645.918345 0.001091 0.09674 0.00724 0.99469 0 12.39341 0.27698 10.98735 0.24556 1.19899 0.08566 1.06431 0.07604 59645.919925 0.000489 0.08137 0.00986 0.98817 0 13.27100 0.42947 11.69577 0.37852 1.07981 0.12614 0.95311 0.11134 59645.921383 0.000969 0.10951 0.00832 0.99104 0 12.22693 0.29221 10.87017 0.25978 1.33897 0.09651 1.19077 0.08584 59645.923432 0.001079 0.09635 0.00727 0.98391 0 12.58670 0.28104 11.19115 0.24990 1.21274 0.08741 1.07721 0.07765 59645.925634 0.001123 0.08367 0.00647 0.98711 0 13.23789 0.28151 11.71203 0.24904 1.10764 0.08233 0.98050 0.07288 59645.927266 0.000509 0.09102 0.01031 0.98295 0 12.74525 0.41419 11.19748 0.36380 1.16007 0.12588 1.02166 0.11081
