/* ** ** Swift/XRT hardness ratio for PKS 1908-201. ** 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 54167.519696 0.463575 0.66602 0.34270 0.00210 0 0.08141 0.03043 0.05546 0.01849 0.05422 0.01917 0.04751 0.01680 54167.528051 0.471880 0.61320 0.10631 0.05666 1 0.03608 0.00398 0.02087 0.00214 0.02213 0.00296 0.01324 0.00170 54168.497505 0.441985 0.67270 0.13191 0.03838 1 0.03493 0.00435 0.02244 0.00279 0.02350 0.00356 0.01507 0.00227 54176.874013 0.103755 0.70114 0.16541 0.10649 1 0.03075 0.00470 0.02295 0.00350 0.02156 0.00388 0.01630 0.00293 55108.695778 0.105558 0.49294 0.08997 0.25808 1 0.03101 0.00325 0.02099 0.00213 0.01529 0.00228 0.01022 0.00148 55391.930651 0.036695 0.62700 0.21513 0.22874 1 0.02003 0.00430 0.01548 0.00332 0.01256 0.00336 0.00969 0.00259 56944.148294 0.067752 0.57212 0.08500 0.33848 1 0.04318 0.00390 0.03217 0.00290 0.02471 0.00292 0.01824 0.00215 56947.420313 0.275498 0.51956 0.07548 0.07751 1 0.04810 0.00412 0.03782 0.00324 0.02499 0.00293 0.01982 0.00232
