/* ** ** Swift/XRT hardness ratio for PKS 2155-304. ** 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 53955.285259 0.000359 0.11129 0.01659 0.99194 0 8.25447 0.38979 7.31849 0.34557 0.91864 0.12992 0.81436 0.11517 53955.286115 0.000498 0.07996 0.01234 0.97093 0 8.05650 0.32962 7.20458 0.29476 0.64423 0.09590 0.57574 0.08567 53955.287056 0.000443 0.09731 0.01441 0.96732 0 7.81747 0.34307 6.95846 0.30536 0.76072 0.10759 0.67680 0.09571 53955.287979 0.000480 0.08697 0.01329 0.96988 0 7.74993 0.32610 6.93866 0.29197 0.67399 0.09901 0.60344 0.08865 53955.289226 0.000767 0.10467 0.01125 0.98210 0 7.96725 0.26192 7.13338 0.23450 0.83392 0.08533 0.74664 0.07640 53955.290729 0.000726 0.10948 0.02600 0.96000 1 6.70741 0.49624 1.50588 0.11141 0.73430 0.16574 0.16525 0.03729 53955.291993 0.000537 0.14327 0.03452 0.94595 1 7.06656 0.59577 1.58300 0.13345 1.01242 0.22849 0.22663 0.05115 53955.293416 0.000886 0.08429 0.01979 0.95082 1 7.24880 0.46743 1.62300 0.10466 0.61099 0.13792 0.13676 0.03086 53955.295218 0.000915 0.08581 0.02053 0.93651 1 6.82086 0.44875 1.53948 0.10128 0.58533 0.13460 0.13214 0.03039 53955.297004 0.000872 0.12148 0.02520 0.93253 1 6.82030 0.46026 1.53076 0.10330 0.82856 0.16250 0.18587 0.03645
