/* ** ** 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 56832.252568 0.000292 0.44315 0.03842 0.98020 0 10.17888 0.48484 9.01718 0.42947 4.51079 0.32682 3.99260 0.28932 56832.253167 0.000307 0.40438 0.03448 0.99057 0 10.54303 0.48197 9.35907 0.42789 4.26338 0.30686 3.78208 0.27221 56832.253804 0.000330 0.37416 0.03230 0.99123 0 10.50454 0.47283 9.21827 0.41492 3.93034 0.28952 3.44746 0.25391 56832.254452 0.000318 0.37292 0.03175 1.00000 0 11.05471 0.49058 9.58678 0.42544 4.12247 0.29951 3.57513 0.25975 56832.255103 0.000333 0.37823 0.03251 0.98261 0 10.51307 0.46956 9.17167 0.40958 3.97635 0.29198 3.46519 0.25453 56832.255765 0.000330 0.36991 0.03227 1.00000 0 10.37114 0.46296 9.14105 0.40808 3.83643 0.28749 3.38610 0.25386 56832.256425 0.000330 0.38838 0.03290 0.99123 0 10.43224 0.46578 9.04835 0.40399 4.05171 0.29162 3.51432 0.25294 56832.257085 0.000330 0.38208 0.03224 0.99123 0 10.59923 0.47176 9.19424 0.40923 4.04979 0.29026 3.51297 0.25179 56832.257730 0.000315 0.41554 0.03575 1.00000 0 9.99255 0.46829 8.73094 0.40921 4.15226 0.29963 3.62491 0.26158 56832.258372 0.000327 0.41410 0.03582 1.00000 0 9.64457 0.45256 8.40123 0.39419 3.99377 0.29018 3.48022 0.25285 56832.259214 0.000515 0.40503 0.02761 0.98516 0 10.01889 0.36590 8.75137 0.31960 4.05796 0.23360 3.54587 0.20413
