/* ** ** 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 57874.412634 0.000379 0.22613 0.03583 0.98473 0 4.01258 0.27305 3.38861 0.23058 0.90738 0.12983 0.76851 0.10996 57874.413383 0.000370 0.22115 0.03494 0.96094 0 4.29438 0.28759 3.64451 0.24407 0.94971 0.13588 0.80599 0.11532 57874.414110 0.000356 0.26146 0.04150 0.94309 0 3.89130 0.28033 3.30253 0.23792 1.01744 0.14389 0.86351 0.12212 57874.414891 0.000425 0.20257 0.03204 0.99320 0 3.94977 0.25903 3.33879 0.21895 0.80009 0.11514 0.67550 0.09722 57874.415701 0.000385 0.20856 0.03303 0.98496 0 4.25374 0.28094 3.60958 0.23840 0.88718 0.12768 0.75284 0.10835 57874.416488 0.000402 0.20773 0.03195 0.95683 0 4.35790 0.27731 3.69803 0.23532 0.90528 0.12676 0.76820 0.10757 57874.417217 0.000327 0.27700 0.04266 0.96460 0 4.22184 0.30437 3.58292 0.25831 1.16943 0.15914 0.99248 0.13506 57874.417920 0.000376 0.23688 0.03758 0.96923 0 3.93472 0.27647 3.33877 0.23460 0.93206 0.13258 0.79089 0.11250 57874.418644 0.000347 0.23634 0.03751 0.99167 0 4.17539 0.29401 3.54337 0.24951 0.98680 0.14037 0.83741 0.11912 57874.419419 0.000428 0.20305 0.03168 0.95270 0 4.14101 0.26335 3.51462 0.22351 0.84082 0.11978 0.71366 0.10166 57874.420192 0.000344 0.24612 0.03901 0.98319 0 4.09913 0.29325 3.47850 0.24885 1.00887 0.14268 0.85613 0.12107 57874.420837 0.000301 0.28902 0.04695 0.97115 0 4.00186 0.30772 3.39617 0.26115 1.15660 0.16548 0.98156 0.14044 57874.421511 0.000373 0.23151 0.03635 0.97674 0 4.04634 0.27607 3.43386 0.23429 0.93678 0.13248 0.79497 0.11243 57874.422194 0.000310 0.29736 0.04795 0.96262 0 3.89111 0.29997 3.30223 0.25458 1.15706 0.16388 0.98195 0.13908 57874.423048 0.000544 0.22114 0.02968 0.97872 0 3.97316 0.22725 3.37182 0.19286 0.87863 0.10667 0.74566 0.09053
