/* ** ** 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 59345.205423 0.000344 0.16838 0.01313 1.00000 0 21.47109 0.63564 19.74527 0.58449 3.61530 0.26070 3.32146 0.23952 59345.206144 0.000376 0.17125 0.01338 0.96923 0 19.79394 0.58157 18.32961 0.53854 3.38978 0.24541 3.13852 0.22723 59345.206867 0.000347 0.16828 0.01312 1.00000 0 21.13250 0.62746 19.57358 0.58117 3.55611 0.25644 3.29378 0.23753 59345.207585 0.000370 0.16031 0.01234 1.00000 0 21.29829 0.61664 19.52356 0.56522 3.41434 0.24344 3.13332 0.22333 59345.208384 0.000428 0.12931 0.01017 1.00000 0 22.09971 0.58200 20.24572 0.53308 2.85771 0.21169 2.62187 0.19413 59345.209246 0.000434 0.13073 0.01003 1.00000 0 21.95341 0.57250 20.13539 0.52505 2.87001 0.20702 2.63503 0.19002 59345.210088 0.000408 0.14325 0.01126 1.00000 0 21.14058 0.58549 19.29902 0.53444 3.02843 0.22278 2.76483 0.20336 59345.210881 0.000385 0.15964 0.01252 0.99248 0 20.31049 0.58831 18.67176 0.54078 3.24234 0.23634 2.98219 0.21733 59345.211673 0.000408 0.14940 0.01159 0.99291 0 20.68966 0.57683 18.91844 0.52733 3.09098 0.22380 2.82467 0.20450 59345.212518 0.000437 0.14170 0.01080 0.98013 0 20.64646 0.55850 19.12482 0.51734 2.92553 0.20852 2.70990 0.19315 59345.213389 0.000434 0.13673 0.01049 0.99333 0 21.32696 0.57037 19.48317 0.52110 2.91597 0.20972 2.66616 0.19177 59345.214188 0.000365 0.16256 0.01242 1.00000 0 21.44503 0.62080 19.57962 0.56681 3.48610 0.24653 3.17990 0.22485 59345.214940 0.000388 0.15743 0.01219 0.99254 0 20.64522 0.59083 18.96819 0.54281 3.25016 0.23374 2.98690 0.21484 59345.215988 0.000660 0.15324 0.00918 0.99561 0 20.66980 0.45423 19.04726 0.41853 3.16750 0.17647 2.91672 0.16250
