/* ** ** Swift/XRT hardness ratio for Mrk 501. ** 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 55725.835954 0.000602 0.37600 0.03171 0.97596 0 5.89155 0.25739 5.17128 0.22594 2.21522 0.15980 1.94267 0.14014 55725.837230 0.000674 0.34393 0.02922 0.98712 0 5.63255 0.23907 4.90133 0.20803 1.93721 0.14257 1.68720 0.12419 55725.838587 0.000683 0.32935 0.02696 0.97881 0 6.03794 0.24492 5.29463 0.21476 1.98859 0.14142 1.74231 0.12390 55725.840002 0.000732 0.30541 0.02505 0.98024 0 5.99822 0.23667 5.22090 0.20600 1.83190 0.13172 1.59441 0.11463 55725.841446 0.000712 0.30997 0.02560 0.98374 0 6.00191 0.24117 5.24634 0.21081 1.86044 0.13422 1.62960 0.11755 55725.842956 0.000799 0.29456 0.02389 0.98913 0 5.62243 0.21835 4.95776 0.19254 1.65616 0.11790 1.45995 0.10392 55725.844525 0.000770 0.27972 0.02292 0.98872 0 6.04991 0.22952 5.33278 0.20231 1.69231 0.12290 1.49148 0.10832 55725.846105 0.000810 0.27941 0.02273 0.98929 0 5.80771 0.22057 5.11975 0.19444 1.62276 0.11676 1.43092 0.10296 55725.847754 0.000839 0.29556 0.02253 0.96552 0 6.18746 0.22491 5.46853 0.19878 1.82878 0.12253 1.61628 0.10830
