/* ** ** 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 56019.188315 0.000692 0.31630 0.02610 0.97908 0 5.93363 0.23699 5.34081 0.21331 1.87679 0.13551 1.68930 0.12196 56019.189660 0.000654 0.31881 0.02605 0.98230 0 6.18902 0.24746 5.64687 0.22578 1.97311 0.14058 1.79959 0.12820 56019.191011 0.000697 0.30899 0.02534 0.97095 0 5.99308 0.23656 5.46654 0.21576 1.85182 0.13314 1.68974 0.12149 56019.192739 0.001030 0.29211 0.02020 0.96649 0 6.11814 0.19870 5.53675 0.17979 1.78719 0.10909 1.61684 0.09869 56019.255603 0.000645 0.33589 0.02781 0.98206 0 6.15029 0.25521 5.38810 0.22355 2.06581 0.14802 1.81051 0.12972 56019.256905 0.000657 0.31801 0.02599 0.99559 0 6.29651 0.25446 5.58682 0.22578 2.00238 0.14227 1.77677 0.12624 56019.258234 0.000671 0.31529 0.02598 0.98276 0 6.21555 0.24993 5.51460 0.22175 1.95970 0.14097 1.73869 0.12507 56019.259611 0.000706 0.30031 0.02452 0.97951 0 6.24169 0.24396 5.53787 0.21646 1.87443 0.13439 1.66303 0.11924 56019.261362 0.001045 0.32487 0.02141 0.97507 0 6.10686 0.19798 5.41999 0.17571 1.98394 0.11380 1.76066 0.10099
