/* ** ** 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 57647.269051 0.000420 0.16814 0.04310 0.98621 0 1.82898 0.17542 1.57476 0.15105 0.30753 0.07310 0.26538 0.06309 57647.269893 0.000422 0.15851 0.03985 0.97260 0 1.97419 0.18108 1.70919 0.15678 0.31293 0.07324 0.27098 0.06342 57647.270845 0.000530 0.12258 0.02996 0.97814 0 2.05250 0.16702 1.77830 0.14470 0.25159 0.05799 0.21792 0.05023 57647.272474 0.001100 0.06615 0.01528 0.98158 0 1.87130 0.10853 1.61967 0.09394 0.12379 0.02768 0.10742 0.02402 57647.274346 0.000773 0.09785 0.02294 0.96255 0 1.84322 0.12987 1.59252 0.11219 0.18037 0.04033 0.15590 0.03486 57647.275617 0.000498 0.19100 0.04801 0.95930 0 1.43621 0.14382 1.23847 0.12403 0.27432 0.06324 0.23641 0.05449 57647.276708 0.000593 0.10728 0.02601 0.96098 0 2.13250 0.16028 1.84512 0.13868 0.22877 0.05272 0.19801 0.04564 57647.277937 0.000637 0.09950 0.02340 0.98182 0 2.14939 0.15690 1.86283 0.13598 0.21385 0.04782 0.18549 0.04148 57647.279210 0.000637 0.18092 0.03574 0.96364 0 1.85272 0.14500 1.60544 0.12565 0.33519 0.06079 0.29044 0.05267
