/* ** ** Swift/XRT hardness ratio for 3C 273. ** 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 55207.092568 0.000804 0.47732 0.04142 0.98561 0 4.26593 0.20976 3.04201 0.14946 2.03623 0.14559 1.44897 0.10352 55207.094217 0.000845 0.48193 0.04206 0.95205 0 4.11798 0.20323 2.93834 0.14501 1.98459 0.14286 1.41875 0.10212 55207.095936 0.000874 0.45865 0.03931 0.96687 0 4.13352 0.19747 2.98345 0.14253 1.89585 0.13491 1.36832 0.09737 55207.097710 0.000900 0.49592 0.04336 0.93891 0 3.78330 0.18899 2.73055 0.13640 1.87621 0.13465 1.35430 0.09719 55207.099568 0.000958 0.46283 0.03986 0.81873 0 4.41543 0.21343 3.18599 0.15400 2.04360 0.14564 1.47240 0.10493 55207.101298 0.000773 0.53436 0.04713 0.98127 0 3.94188 0.20559 2.84577 0.14842 2.10637 0.14983 1.52131 0.10821 55207.102852 0.000781 0.47523 0.04108 0.96296 0 4.47584 0.21833 3.22648 0.15737 2.12707 0.15181 1.53270 0.10939 55207.104336 0.000703 0.54074 0.04788 0.97119 0 4.31063 0.22840 3.13692 0.16621 2.33094 0.16538 1.69740 0.12043 55207.105713 0.000674 0.60271 0.05448 0.98712 0 3.96223 0.22083 2.88249 0.16065 2.38806 0.16994 1.73715 0.12361 55207.107157 0.000770 0.52647 0.04651 0.97744 0 4.00169 0.20852 2.90465 0.15135 2.10676 0.15029 1.52900 0.10908 55207.108891 0.000964 0.44676 0.03422 0.97769 0 4.72048 0.20101 3.43979 0.14646 2.10892 0.13427 1.53622 0.09780 55207.161120 0.000642 0.43911 0.03763 0.98649 0 4.59548 0.21712 4.14222 0.19570 2.01790 0.14426 1.81927 0.13005 55207.162413 0.000651 0.42519 0.03656 0.99556 0 4.57324 0.21554 4.15080 0.19563 1.94450 0.13983 1.76497 0.12692 55207.163628 0.000564 0.52043 0.04594 0.98974 0 4.36020 0.22616 3.95724 0.20526 2.26920 0.16208 2.05948 0.14710 55207.164846 0.000654 0.51350 0.04321 0.98230 0 4.25411 0.20666 3.86085 0.18756 2.18450 0.15008 1.98254 0.13620
