/* ** ** 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 59792.847022 0.000512 0.24135 0.03878 0.94915 0 7.46093 0.52916 2.42568 0.17172 1.80070 0.25964 0.58700 0.08449 59792.847945 0.000411 0.27671 0.04468 0.92958 0 7.81761 0.59704 2.73291 0.20870 2.16319 0.30772 0.75492 0.10739 59792.848830 0.000475 0.22368 0.03533 0.96341 0 8.10223 0.55602 2.81653 0.19325 1.81234 0.25779 0.63069 0.08972 59792.850008 0.000703 0.29806 0.03660 0.94190 0 7.30438 0.43575 2.56674 0.15311 2.17712 0.23364 0.76572 0.08217 59792.916213 0.000752 0.26533 0.02135 0.98846 0 6.65892 0.24913 5.85720 0.21911 1.76678 0.12583 1.55483 0.11073 59792.918218 0.001247 0.23588 0.01524 0.98776 0 6.88360 0.19528 5.98286 0.16971 1.62371 0.09424 1.41149 0.08192 59792.962493 0.000761 0.25515 0.02035 0.98479 0 6.76222 0.24341 6.05252 0.21784 1.72539 0.12278 1.54363 0.10985 59792.964605 0.001351 0.26653 0.01620 0.97002 0 6.57088 0.18380 5.88050 0.16447 1.75134 0.09454 1.56711 0.08456
