/* ** ** Swift/XRT hardness ratio for 1ES 1218+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 56589.229869 0.000411 0.25644 0.06597 0.96479 0 1.34648 0.15418 1.11323 0.12744 0.34530 0.07955 0.28506 0.06560 56589.230624 0.000344 0.24101 0.06097 0.97479 0 1.71465 0.19221 1.41943 0.15907 0.41325 0.09372 0.34103 0.07736 56589.231310 0.000341 0.34171 0.09039 0.98305 0 1.20287 0.16355 0.99685 0.13554 0.41103 0.09326 0.34103 0.07736 56589.232158 0.000506 0.21661 0.05414 0.96571 0 1.30523 0.13702 1.08401 0.11380 0.28273 0.06414 0.23408 0.05310 56589.232980 0.000315 0.41458 0.10786 0.97248 0 1.15763 0.16394 0.95430 0.13514 0.47993 0.10474 0.39689 0.08661 56589.234007 0.000712 0.27164 0.05043 0.96233 0 1.39543 0.12029 1.15366 0.09944 0.37905 0.06232 0.31311 0.05148
