/* ** ** 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 56555.018885 0.000628 0.65251 0.18868 0.98157 0 0.39494 0.07239 0.28791 0.05276 0.25770 0.05763 0.18811 0.04206 56555.020352 0.000839 0.55297 0.15457 0.96207 0 0.35400 0.05937 0.25881 0.04341 0.19575 0.04377 0.14361 0.03211 56555.021999 0.000807 0.71262 0.21238 0.98925 0 0.27546 0.05302 0.19959 0.03841 0.19630 0.04467 0.14284 0.03249 56555.023414 0.000608 0.86386 0.26597 0.98095 0 0.31023 0.06565 0.22717 0.04807 0.26800 0.05993 0.19450 0.04349 56555.025104 0.001076 0.66061 0.19224 0.97043 0 0.22742 0.04200 0.16701 0.03084 0.15024 0.03378 0.11039 0.02482 56555.026707 0.000527 0.84368 0.25795 0.97253 0 0.36418 0.07594 0.26789 0.05586 0.30725 0.06870 0.22637 0.05062 56555.028530 0.001291 0.52027 0.12388 0.96861 0 0.32769 0.04594 0.24033 0.03369 0.17049 0.03281 0.12521 0.02410
