/* ** ** 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 55236.215969 0.000391 0.19271 0.04139 0.97037 0 2.45593 0.21502 2.07258 0.18145 0.47329 0.09282 0.39761 0.07798 55236.216672 0.000312 0.18349 0.04478 1.00000 0 2.35433 0.23016 2.02145 0.19761 0.43200 0.09660 0.37099 0.08296 55236.217277 0.000292 0.21820 0.05407 1.00000 0 2.12124 0.22658 1.81833 0.19423 0.46284 0.10350 0.39670 0.08870 55236.218136 0.000567 0.23992 0.03848 0.96328 0 2.53792 0.17933 2.17596 0.15376 0.60890 0.08767 0.52218 0.07518 55236.219013 0.000310 0.18721 0.04619 0.94393 0 2.43696 0.23579 2.09037 0.20226 0.45623 0.10355 0.39149 0.08886 55236.219928 0.000605 0.22344 0.03508 1.00000 0 2.50072 0.17051 2.14449 0.14622 0.55875 0.07902 0.47927 0.06778 55236.220888 0.000356 0.15869 0.03880 0.97561 0 2.42275 0.22012 2.07636 0.18865 0.38448 0.08727 0.32951 0.07479 55236.221551 0.000307 0.16766 0.04131 1.00000 0 2.59597 0.24906 2.22491 0.21346 0.43524 0.09879 0.37303 0.08467 55236.222407 0.000550 0.25218 0.04079 0.96842 0 2.46597 0.17756 2.11338 0.15218 0.62186 0.09008 0.53295 0.07720 55236.223261 0.000304 0.15699 0.03776 0.96190 0 2.95001 0.26146 2.52652 0.22393 0.46313 0.10356 0.39670 0.08870 55236.224112 0.000541 0.25295 0.04068 0.96791 0 2.51252 0.17995 2.15330 0.15422 0.63554 0.09151 0.54469 0.07843 55236.224994 0.000341 0.16079 0.03895 0.97458 0 2.52812 0.23544 2.16690 0.20180 0.40648 0.09089 0.34841 0.07791 55236.225978 0.000642 0.21480 0.03352 0.96396 0 2.54139 0.16760 2.17897 0.14370 0.54588 0.07720 0.46807 0.06620 55236.226973 0.000353 0.16658 0.03871 0.90984 0 2.74807 0.23453 2.35517 0.20100 0.45777 0.09893 0.39232 0.08479 55236.228246 0.000920 0.19662 0.02641 0.96855 0 2.59436 0.14087 2.22345 0.12073 0.51010 0.06268 0.43717 0.05372
