/* ** ** Swift/XRT hardness ratio for Cen A. ** 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 58281.118102 0.000581 17.93058 11.60842 0.95000 1 0.06176 0.03901 0.02899 0.01832 1.10736 0.15702 0.52502 0.07444 58281.119307 0.000625 6.66097 2.69084 0.97674 1 0.15251 0.05765 0.07180 0.02714 1.01589 0.14483 0.47268 0.06737 58281.120353 0.000421 38.76604 39.15593 0.96552 1 0.03965 0.03965 0.01818 0.01818 1.53699 0.21853 0.71078 0.10105 58281.121210 0.000436 42.53563 42.94886 0.96667 1 0.03583 0.03583 0.01667 0.01667 1.52390 0.21293 0.71216 0.09951 58281.122053 0.000407 16.59683 10.75409 0.96429 1 0.09407 0.05943 0.04407 0.02785 1.56124 0.22499 0.72800 0.10487 58281.122953 0.000494 9.30795 4.36905 1.00000 1 0.13541 0.06056 0.06250 0.02795 1.26043 0.17966 0.58390 0.08323 58281.123796 0.000349 12.12831 6.30161 1.00000 1 0.14808 0.07405 0.06957 0.03478 1.79598 0.25346 0.84386 0.11908 58281.124580 0.000436 15.20426 9.05023 0.96667 1 0.09986 0.05772 0.04444 0.02566 1.51826 0.21603 0.68627 0.09756 58281.125481 0.000465 8.54698 4.10625 0.96875 1 0.16556 0.07609 0.07803 0.03583 1.41508 0.19817 0.65807 0.09215 58281.126468 0.000523 3.97593 1.27887 0.97222 1 0.31445 0.09078 0.14546 0.04199 1.25023 0.17734 0.57584 0.08168 58281.423940 0.296920 6.54809 2.20692 0.00228 1 0.20417 0.06457 0.09611 0.03039 1.33695 0.15578 0.63810 0.07434 58281.721253 0.000392 14.13737 8.78118 1.00000 1 0.10927 0.06608 0.05226 0.03158 1.54479 0.21908 0.73888 0.10477 58281.722124 0.000479 3.49957 1.10034 1.00000 1 0.35941 0.10072 0.17166 0.04810 1.25779 0.17932 0.60149 0.08575 58281.722952 0.000349 11.48253 5.96700 1.00000 1 0.15933 0.07968 0.07619 0.03810 1.82948 0.25831 0.84371 0.11908 58281.723722 0.000421 4.31459 1.45231 0.96552 1 0.35102 0.10714 0.16729 0.05106 1.51450 0.21488 0.71958 0.10210 58281.724652 0.000508 6.54759 2.64890 0.94286 1 0.19779 0.07496 0.09371 0.03550 1.29503 0.18329 0.61208 0.08662 58281.725770 0.000610 7.96194 2.81047 0.96061 1 0.19602 0.06534 0.09231 0.03077 1.56066 0.18120 0.73983 0.08589
