/* ** ** 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 58124.439141 0.000124 0.23920 0.01897 1.00000 0 43.57155 1.51542 38.97921 1.35570 10.42221 0.74285 9.32806 0.66475 58124.439818 0.000553 0.28144 0.01038 1.00000 0 41.45916 0.71080 36.46840 0.62520 11.66839 0.38085 10.25410 0.33465 58124.440941 0.000570 0.25832 0.00932 1.00000 0 44.79009 0.73168 38.94411 0.63618 11.57005 0.37217 10.06281 0.32368 58124.442066 0.000556 0.26805 0.00974 1.00000 0 43.80218 0.73247 38.39480 0.64199 11.74103 0.37887 10.29586 0.33220 58124.442741 0.000119 0.25614 0.02035 1.00000 0 44.19450 1.60649 38.55809 1.40174 11.31998 0.79967 9.87544 0.69753 58124.442981 0.000122 0.25007 0.02015 1.00000 0 43.33636 1.56723 38.00854 1.37452 10.83726 0.78027 9.51295 0.68488 58124.443224 0.000122 0.24921 0.01987 1.00000 0 44.02176 1.57418 38.94228 1.39246 10.97052 0.78179 9.70374 0.69149 58124.443467 0.000122 0.24027 0.01904 1.00000 0 46.05259 1.62145 40.37539 1.42162 11.06501 0.78557 9.69850 0.68854 58124.444017 0.000428 0.26282 0.01112 0.99492 0 42.93718 0.82781 37.68921 0.72658 11.28478 0.42512 9.89828 0.37286
