/* ** ** 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 55852.059863 0.000367 0.24544 0.03961 0.98425 0 3.70754 0.26249 3.19433 0.22614 0.90997 0.13197 0.78383 0.11366 55852.060549 0.000318 0.27248 0.04386 0.96364 0 3.96791 0.29180 3.43020 0.25225 1.08116 0.15482 0.93465 0.13384 55852.061182 0.000315 0.25253 0.04047 0.98165 0 4.23841 0.30503 3.66620 0.26385 1.07033 0.15327 0.92591 0.13259 55852.061833 0.000336 0.29424 0.04466 0.99138 0 3.87849 0.28236 3.35802 0.24446 1.14120 0.15198 0.98820 0.13161 55852.062464 0.000295 0.25490 0.04093 0.99020 0 4.45138 0.32320 3.84817 0.27941 1.13468 0.16248 0.98092 0.14046 55852.063894 0.001134 0.28344 0.02292 0.97194 0 4.25615 0.16093 3.67334 0.13889 1.20635 0.08624 1.04157 0.07446 55852.066104 0.001076 0.29689 0.02407 0.96237 0 4.31856 0.16522 3.73369 0.14284 1.28212 0.09165 1.10848 0.07924 55852.067496 0.000315 0.24262 0.03889 0.96330 0 4.47361 0.31405 3.86747 0.27150 1.08540 0.15640 0.93834 0.13521 55852.069669 0.001858 0.31784 0.01955 0.97040 0 4.13408 0.12402 3.57102 0.10712 1.31399 0.07055 1.13539 0.06096
