/* ** ** 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 53952.137949 0.000489 0.09373 0.01371 0.95858 0 7.43450 0.31506 6.72767 0.28511 0.69685 0.09758 0.63068 0.08831 53952.138999 0.000561 0.08167 0.01227 0.95876 0 7.17160 0.29043 6.47476 0.26220 0.58571 0.08477 0.52849 0.07649 53952.139937 0.000376 0.12361 0.01873 0.96154 0 7.18020 0.35489 6.48221 0.32038 0.88753 0.12717 0.80242 0.11494 53952.140808 0.000495 0.08466 0.01260 0.95906 0 7.89578 0.32314 7.14689 0.29249 0.66845 0.09563 0.60508 0.08656 53952.141890 0.000587 0.07705 0.01169 0.96059 0 7.16401 0.28403 6.48055 0.25694 0.55197 0.08083 0.49931 0.07312 53952.142967 0.000489 0.10309 0.01461 0.98896 0 7.06614 0.30914 6.39465 0.27976 0.72843 0.09822 0.65925 0.08889 53952.144060 0.000596 0.12859 0.03052 0.97561 1 6.08003 0.48391 1.55641 0.12387 0.78186 0.17483 0.20000 0.04472 53952.145527 0.000872 0.07929 0.01871 0.98333 1 6.59841 0.42051 1.68298 0.10725 0.52317 0.11885 0.13360 0.03035 53952.147111 0.000712 0.10580 0.02487 0.95918 1 6.33293 0.45835 1.60910 0.11645 0.67001 0.14982 0.17021 0.03806 53952.148534 0.000712 0.11091 0.02612 0.95918 1 6.02151 0.44605 1.53532 0.11373 0.66782 0.14933 0.17021 0.03806 53952.150292 0.001046 0.09818 0.01857 0.95706 1 7.13909 0.40198 1.82239 0.10261 0.70090 0.12653 0.17910 0.03233
