/* ** ** 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 56495.123332 0.000501 0.45843 0.04053 0.97688 0 8.55554 0.41606 5.16859 0.24699 3.92215 0.28960 2.32200 0.16853 56495.124261 0.000428 0.48976 0.04360 1.00000 0 8.63530 0.44119 5.39354 0.27536 4.22924 0.30830 2.64451 0.19257 56495.125158 0.000469 0.55444 0.04981 0.96296 0 7.07303 0.37413 4.53386 0.23979 3.92157 0.28481 2.51550 0.18257 56495.126104 0.000477 0.54276 0.04846 0.98788 0 7.11026 0.37665 4.47463 0.23701 3.85919 0.27735 2.42645 0.17439 56495.127073 0.000492 0.51974 0.04641 0.97647 0 7.25355 0.37706 4.54083 0.23601 3.76992 0.27375 2.36397 0.17157 56495.128121 0.000556 0.46565 0.04060 0.97396 0 7.05165 0.34554 4.51873 0.22144 3.28361 0.23683 2.10952 0.15211 56495.129122 0.000446 0.58240 0.05341 0.99351 0 6.95135 0.38756 4.38908 0.24470 4.04846 0.29481 2.55809 0.18627 56495.130071 0.000503 0.52486 0.04773 0.97701 0 6.92311 0.36733 4.35279 0.23095 3.63368 0.26834 2.28374 0.16861 56495.131136 0.000561 0.50491 0.04461 0.99485 0 6.42222 0.32999 4.06266 0.20870 3.24264 0.23304 2.04928 0.14728 56495.132221 0.000518 0.48924 0.04334 0.99441 0 7.05116 0.36011 4.52833 0.23126 3.44968 0.24971 2.21585 0.16040 56495.133228 0.000489 0.57218 0.05208 0.98225 0 6.41057 0.35142 4.17415 0.22867 3.66801 0.26655 2.37568 0.17264 56495.134197 0.000480 0.62689 0.05584 0.98193 0 6.42401 0.35659 4.07781 0.22629 4.02716 0.28053 2.56201 0.17844
