/* ** ** 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 56811.680167 0.000570 0.13818 0.02097 0.96447 0 4.40748 0.23319 3.79550 0.20080 0.60904 0.08664 0.52443 0.07461 56811.681058 0.000321 0.09324 0.02310 0.98198 0 4.36484 0.30604 3.74129 0.26229 0.40699 0.09670 0.34833 0.08276 56811.681744 0.000365 0.09462 0.02242 0.94444 0 4.05258 0.27573 3.51699 0.23927 0.38344 0.08702 0.33229 0.07542 56811.682436 0.000327 0.09306 0.02207 0.97345 0 4.45480 0.30593 3.85670 0.26485 0.41455 0.09411 0.35947 0.08159 56811.683477 0.000715 0.11013 0.01712 0.95547 0 4.11385 0.19959 3.58292 0.17383 0.45304 0.06693 0.39452 0.05828 56811.684502 0.000310 0.10447 0.02456 0.98131 0 4.19240 0.30458 3.65234 0.26534 0.43798 0.09793 0.38159 0.08533 56811.685315 0.000503 0.15622 0.02435 0.98851 0 4.19226 0.24156 3.64978 0.21030 0.65490 0.09486 0.57016 0.08258 56811.686345 0.000527 0.14104 0.02143 0.97802 0 4.54874 0.24229 3.96670 0.21129 0.64156 0.09127 0.55979 0.07964 56811.687314 0.000443 0.06744 0.01561 0.97386 0 4.57941 0.27285 3.98765 0.23759 0.30884 0.06906 0.26890 0.06013 56811.688367 0.000611 0.13632 0.02069 0.99052 0 4.01158 0.21241 3.49750 0.18519 0.54686 0.07780 0.47676 0.06783 56811.689629 0.000651 0.12037 0.01821 0.96444 0 4.35113 0.21393 3.79460 0.18657 0.52373 0.07495 0.45676 0.06537 56811.690592 0.000312 0.08993 0.02132 0.99074 0 4.70917 0.32333 4.10933 0.28215 0.42351 0.09612 0.36955 0.08387
