/* ** ** 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 55248.603547 0.000324 0.33900 0.05409 0.97321 0 3.36523 0.27187 2.89164 0.23357 1.14083 0.15699 0.98278 0.13523 55248.604484 0.000613 0.31786 0.03641 0.96698 0 3.61937 0.20288 3.10680 0.17414 1.15047 0.11492 0.98904 0.09880 55248.605428 0.000330 0.26044 0.04190 0.99123 0 3.87852 0.28509 3.36920 0.24765 1.01011 0.14458 0.87707 0.12553 55248.606119 0.000362 0.25895 0.04075 0.99200 0 3.68540 0.26458 3.18710 0.22880 0.95433 0.13364 0.82395 0.11538 55248.606868 0.000388 0.25337 0.04005 0.96269 0 3.52457 0.24884 3.06487 0.21638 0.89302 0.12629 0.77649 0.10981 55248.607560 0.000304 0.29300 0.04812 0.97143 0 3.77289 0.29193 3.28081 0.25385 1.10547 0.16015 0.96129 0.13927 55248.608197 0.000333 0.29366 0.04762 0.99130 0 3.42294 0.26626 2.97644 0.23153 1.00520 0.14301 0.87402 0.12435 55248.608868 0.000339 0.33494 0.05218 0.98291 0 3.36152 0.26389 2.92325 0.22949 1.12592 0.15151 0.97917 0.13176 55248.609554 0.000347 0.27677 0.04503 0.98333 0 3.49135 0.26436 3.02070 0.22871 0.96629 0.13917 0.83543 0.12030 55248.610439 0.000538 0.32975 0.04055 0.97312 0 3.45970 0.21069 2.98448 0.18175 1.14082 0.12188 0.98445 0.10516 55248.611275 0.000298 0.32415 0.05372 0.98058 0 3.50504 0.28770 3.01335 0.24733 1.13617 0.16358 0.97605 0.14055 55248.611964 0.000391 0.31319 0.04442 0.98519 0 3.63571 0.25254 3.16149 0.21960 1.13869 0.14080 0.99016 0.12243 55248.612661 0.000307 0.30459 0.04971 0.95283 0 3.73048 0.29254 3.21996 0.25250 1.13626 0.16262 0.98128 0.14045 55248.613304 0.000336 0.26691 0.04325 0.97414 0 3.75880 0.27932 3.26847 0.24289 1.00325 0.14446 0.87240 0.12562 55248.614218 0.000579 0.32901 0.03873 0.97500 0 3.47393 0.20508 3.02063 0.17832 1.14296 0.11641 0.99382 0.10122 55248.615237 0.000440 0.28898 0.03807 0.99342 0 3.94579 0.24678 3.43121 0.21459 1.14024 0.13219 0.99153 0.11495 55248.616003 0.000327 0.26472 0.04181 0.96460 0 4.05069 0.28962 3.52273 0.25187 1.07229 0.15104 0.93249 0.13134 55248.616831 0.000501 0.33950 0.04406 0.98266 0 3.22006 0.21223 2.77711 0.18302 1.09320 0.12223 0.94275 0.10540
