/* ** ** Swift/XRT hardness ratio for Mrk 501. ** 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 55229.988352 0.000347 0.14642 0.03422 0.96667 0 2.88454 0.24126 2.47688 0.20715 0.42235 0.09217 0.36267 0.07914 55229.989411 0.000712 0.18653 0.02848 0.97154 0 2.67068 0.16237 2.29320 0.13942 0.49816 0.06976 0.42749 0.05986 55229.990612 0.000489 0.27878 0.04446 0.97633 0 2.56130 0.19157 2.20567 0.16496 0.71405 0.10059 0.61595 0.08677 55229.991407 0.000307 0.17526 0.04255 0.98113 0 2.54069 0.24031 2.19825 0.20792 0.44528 0.09957 0.38526 0.08615 55229.992426 0.000712 0.21465 0.03342 0.95528 0 2.30037 0.14969 1.98546 0.12920 0.49377 0.06983 0.42624 0.06028 55229.993771 0.000634 0.18182 0.02817 0.98630 0 2.94651 0.18063 2.53231 0.15522 0.53574 0.07623 0.46124 0.06563 55229.994981 0.000576 0.21504 0.03412 0.97487 0 2.74662 0.18256 2.35844 0.15676 0.59063 0.08509 0.50800 0.07318 55229.995861 0.000304 0.19660 0.04803 0.96190 0 2.33016 0.22916 2.01756 0.19842 0.45811 0.10244 0.39670 0.08870 55229.996700 0.000535 0.25448 0.04029 0.96216 0 2.56171 0.18227 2.20787 0.15708 0.65192 0.09220 0.56273 0.07958 55229.997767 0.000532 0.26587 0.04271 0.97283 0 2.43058 0.18131 2.09681 0.15639 0.64621 0.09195 0.55658 0.07920 55229.999136 0.000836 0.18836 0.02663 0.96194 0 2.64113 0.14817 2.28590 0.12824 0.49747 0.06455 0.43044 0.05585
