/* ** ** Swift/XRT hardness ratio for BL Lacertae. ** 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 56421.976791 0.000816 0.40774 0.10932 0.98582 0 0.46376 0.06765 0.35133 0.05125 0.18909 0.04254 0.14331 0.03224 56421.978417 0.000810 0.57927 0.16369 0.97857 0 0.33564 0.05797 0.25152 0.04344 0.19443 0.04348 0.14623 0.03270 56421.979956 0.000729 0.72339 0.22023 0.97222 0 0.28935 0.05754 0.21968 0.04369 0.20932 0.04825 0.15890 0.03663 56421.981449 0.000764 0.63688 0.18323 0.96212 0 0.32708 0.05921 0.24759 0.04481 0.20831 0.04658 0.15774 0.03527 56421.982844 0.000631 0.53299 0.14918 0.97248 0 0.46819 0.07882 0.35541 0.05983 0.24954 0.05580 0.18899 0.04226 56421.984372 0.000897 0.48400 0.13306 0.96774 0 0.36188 0.05719 0.27442 0.04336 0.17515 0.03940 0.13280 0.02987 56421.986374 0.001105 0.55362 0.12980 0.97382 0 0.37242 0.05292 0.28167 0.04003 0.20618 0.03845 0.15556 0.02901
