/* ** ** 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 57875.025169 0.000344 0.23641 0.05672 0.93277 0 3.26069 0.34005 1.65509 0.17260 0.77085 0.16654 0.39237 0.08478 57875.026121 0.000608 0.27254 0.04436 0.98571 0 3.48324 0.26457 1.74472 0.13252 0.94932 0.13666 0.47636 0.06857 57875.027321 0.000593 0.21829 0.03431 0.97073 0 4.63490 0.30985 2.29335 0.15331 1.01176 0.14395 0.50074 0.07123 57875.028505 0.000590 0.22718 0.03606 0.98529 0 4.33454 0.29720 2.17109 0.14884 0.98471 0.14095 0.49317 0.07057 57875.029596 0.000501 0.22385 0.03590 1.00000 0 5.00317 0.34551 2.53593 0.17510 1.11995 0.16213 0.56697 0.08210 57875.030658 0.000561 0.19183 0.03434 0.98454 0 4.16677 0.30389 2.06672 0.15072 0.79933 0.13066 0.39585 0.06471 57875.031887 0.000668 0.20016 0.03143 0.96970 0 4.44630 0.28711 2.21514 0.14302 0.88997 0.12737 0.44253 0.06332 57875.033117 0.000561 0.25374 0.04019 0.95361 0 4.29792 0.30423 2.15326 0.15241 1.09057 0.15450 0.54665 0.07744 57875.034196 0.000518 0.33117 0.05319 0.96089 0 3.65669 0.29489 1.84617 0.14888 1.21097 0.16819 0.61126 0.08490
