/* ** ** Swift/XRT hardness ratio for PKS 0521-36. ** 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 57234.014778 0.001278 0.71609 0.21298 1.00000 1 0.33225 0.06470 0.12512 0.02417 0.23792 0.05349 0.09091 0.02033 57234.018438 0.002382 0.59431 0.12066 0.97396 1 0.43876 0.05427 0.16351 0.02022 0.26076 0.04198 0.09717 0.01564 57234.348251 0.000813 0.45261 0.11924 0.98214 1 0.41212 0.06082 0.33810 0.04989 0.18653 0.04071 0.15273 0.03333 57234.350140 0.001075 0.30698 0.07882 0.98649 1 0.43265 0.05366 0.35617 0.04418 0.13281 0.02986 0.10903 0.02451 57234.352682 0.001467 0.47105 0.09929 0.95060 1 0.35512 0.04221 0.29236 0.03475 0.16728 0.02912 0.13748 0.02393
