/* ** ** 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 55370.004515 0.000538 0.07818 0.01815 0.97849 0 3.52258 0.22017 2.81460 0.17590 0.27540 0.06159 0.22015 0.04923 55370.005536 0.000483 0.09730 0.02282 0.95808 0 3.17818 0.22499 2.56171 0.18134 0.30924 0.06915 0.25042 0.05600 55370.006517 0.000498 0.09951 0.02336 0.98256 0 2.95888 0.21139 2.37011 0.16932 0.29444 0.06584 0.23708 0.05301 55370.007350 0.000336 0.12279 0.02955 0.95690 0 3.61736 0.28611 2.91123 0.23020 0.44419 0.10097 0.35590 0.08087 55370.008013 0.000327 0.13023 0.03101 0.94690 0 3.57881 0.29262 2.86827 0.23444 0.46607 0.10423 0.37446 0.08373 55370.008884 0.000544 0.07938 0.01875 0.98936 0 3.31035 0.21374 2.67309 0.17258 0.26276 0.05971 0.21239 0.04826 55370.009830 0.000402 0.11482 0.02719 0.98561 0 3.16451 0.24648 2.54773 0.19845 0.36335 0.08125 0.29246 0.06540 55370.010933 0.000700 0.06907 0.01598 0.96281 0 3.10824 0.18356 2.47324 0.14605 0.21468 0.04801 0.17196 0.03845 55370.012078 0.000446 0.10413 0.02487 0.98701 0 3.13148 0.22975 2.48889 0.18258 0.32608 0.07410 0.25990 0.05906 55370.013071 0.000547 0.09445 0.02208 0.95767 0 2.93450 0.19939 2.34643 0.15941 0.27718 0.06198 0.22136 0.04950 55370.014055 0.000437 0.09556 0.02238 0.99338 0 3.51001 0.24498 2.80302 0.19563 0.33540 0.07500 0.26711 0.05973 55370.014955 0.000463 0.09863 0.02312 0.97500 0 3.25068 0.22807 2.60330 0.18263 0.32060 0.07169 0.25684 0.05743 55370.015881 0.000463 0.10175 0.02390 0.98750 0 3.13466 0.22531 2.50146 0.17980 0.31896 0.07132 0.25359 0.05670 55370.016838 0.000495 0.08333 0.01938 0.95906 0 3.66925 0.23452 2.92319 0.18683 0.30576 0.06837 0.24431 0.05463
