/* ** ** 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 57185.974967 0.001444 0.06743 0.01561 0.98397 0 1.68621 0.09937 1.20387 0.07088 0.11371 0.02545 0.08160 0.01825 57185.977198 0.000787 0.11223 0.02763 0.97794 0 1.77178 0.13718 1.29252 0.10007 0.19885 0.04648 0.14481 0.03385 57185.978914 0.000929 0.11271 0.02664 0.98442 0 1.54312 0.11816 1.12536 0.08618 0.17392 0.03889 0.12679 0.02835 57185.980702 0.000859 0.11981 0.02838 0.97643 0 1.57701 0.12326 1.15481 0.09026 0.18894 0.04225 0.13816 0.03089 57185.982323 0.000761 0.13654 0.03260 0.96958 0 1.58146 0.13253 1.15224 0.09656 0.21593 0.04828 0.15712 0.03513 57185.983946 0.000862 0.11968 0.02840 0.98322 0 1.56634 0.12452 1.14272 0.09084 0.18745 0.04192 0.13675 0.03058 57185.985789 0.000981 0.12697 0.02760 0.98820 0 1.59599 0.11669 1.15261 0.08426 0.20264 0.04149 0.14642 0.02998
