/* ** ** 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 56074.059091 0.000385 0.28972 0.04884 0.97744 0 4.99103 0.40083 2.52210 0.20189 1.44601 0.21432 0.74253 0.10948 56074.059904 0.000428 0.31043 0.05131 0.96622 0 4.54991 0.36895 2.23905 0.18148 1.41243 0.20342 0.68956 0.09926 56074.060665 0.000333 0.38093 0.06484 0.96522 0 4.65143 0.41610 2.33854 0.20898 1.77186 0.25661 0.88368 0.12796 56074.061319 0.000321 0.45337 0.07786 0.95495 0 4.25645 0.40681 2.10621 0.20126 1.92976 0.27536 0.95825 0.13672 56074.061938 0.000298 0.40950 0.06954 0.98058 0 4.97005 0.46076 2.40652 0.22309 2.03522 0.28957 0.98660 0.14035 56074.063075 0.000833 0.38707 0.03925 0.96116 0 5.32692 0.28795 2.59648 0.14032 2.06187 0.17688 1.00005 0.08577 56074.083924 0.000558 0.38005 0.03218 0.98446 0 6.13004 0.27090 5.48293 0.24232 2.32969 0.16823 2.08617 0.15065 56074.085027 0.000544 0.37469 0.03148 1.00000 0 6.32882 0.27971 5.66075 0.25018 2.37133 0.16945 2.11978 0.15148 56074.086520 0.000949 0.36268 0.02357 0.97805 0 6.34245 0.21154 5.69561 0.18997 2.30030 0.12827 2.06569 0.11519 56074.126681 0.001123 0.33321 0.02655 0.96649 0 9.62027 0.38046 3.42395 0.13530 3.20552 0.22168 1.14125 0.07885
