/* ** ** 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 55015.946198 0.000561 0.24167 0.03878 0.94845 0 3.43365 0.23814 2.24976 0.15516 0.82981 0.12009 0.53596 0.07714 55015.947323 0.000564 0.25368 0.04038 0.95897 0 3.64980 0.26069 2.09675 0.14973 0.92589 0.13173 0.53289 0.07580 55015.948394 0.000506 0.25958 0.04149 0.97714 0 3.87731 0.28245 2.24436 0.16346 1.00649 0.14318 0.58275 0.08290 55015.949401 0.000501 0.25745 0.04134 0.97688 0 4.02001 0.29305 2.28263 0.16638 1.03497 0.14809 0.58659 0.08393 55015.950417 0.000515 0.23514 0.03779 0.97753 0 4.24830 0.29612 2.39109 0.16666 0.99895 0.14466 0.56380 0.08163 55015.951533 0.000602 0.22006 0.03526 0.96635 0 3.89074 0.25980 2.20695 0.14734 0.85621 0.12472 0.48549 0.07071 55015.952708 0.000573 0.22264 0.03504 0.98990 0 3.98743 0.26828 2.28130 0.15348 0.88776 0.12630 0.50842 0.07232 55015.953848 0.000567 0.22673 0.03582 0.98469 0 4.03149 0.27680 2.27138 0.15592 0.91406 0.13006 0.51632 0.07345 55015.954896 0.000480 0.26889 0.04282 0.94578 0 4.12516 0.30185 2.37278 0.17360 1.10921 0.15690 0.63801 0.09023 55015.956004 0.000628 0.23840 0.03786 0.96774 0 3.39434 0.23914 1.97814 0.13929 0.80922 0.11516 0.47453 0.06750 55015.957127 0.000495 0.25534 0.04088 0.94737 0 4.10047 0.29416 2.38522 0.17102 1.04702 0.14984 0.61194 0.08756 55015.958113 0.000492 0.24966 0.04038 0.98824 0 4.07100 0.29922 2.34455 0.17227 1.01638 0.14642 0.58701 0.08449 55015.959088 0.000483 0.26207 0.04206 0.97605 0 3.91626 0.29076 2.32447 0.17253 1.02632 0.14601 0.61135 0.08696 55015.960156 0.000584 0.19982 0.03130 0.96535 0 4.39192 0.28012 2.54984 0.16259 0.87757 0.12555 0.50838 0.07274 55015.961293 0.000553 0.23511 0.03716 0.97382 0 3.91996 0.26985 2.29005 0.15762 0.92162 0.13113 0.53575 0.07621 55015.962387 0.000541 0.20051 0.03165 0.95722 0 4.77160 0.30896 2.74088 0.17742 0.95677 0.13772 0.55093 0.07930 55015.963394 0.000466 0.32447 0.04879 0.98758 0 3.92057 0.29777 2.31883 0.17610 1.27211 0.16510 0.75273 0.09765
