/* ** ** 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 55187.822828 0.000550 0.22779 0.03640 0.98947 0 3.02258 0.21395 2.24856 0.15715 0.68852 0.09862 0.53001 0.07540 55187.823904 0.000527 0.22889 0.03593 0.98901 0 3.12338 0.21278 2.43875 0.16611 0.71490 0.10111 0.55648 0.07870 55187.824992 0.000561 0.22604 0.03562 0.96907 0 3.01097 0.20410 2.34566 0.15900 0.68061 0.09682 0.53001 0.07540 55187.826132 0.000579 0.21842 0.03455 0.97500 0 3.00969 0.20290 2.32756 0.15690 0.65738 0.09408 0.50830 0.07274 55187.827081 0.000370 0.31892 0.05294 0.97656 0 3.18536 0.25833 2.46317 0.19975 1.01586 0.14715 0.78456 0.11364 55187.827784 0.000333 0.14618 0.03545 0.96522 0 3.12995 0.26735 2.43725 0.20818 0.45753 0.10384 0.35624 0.08085 55187.828580 0.000463 0.28219 0.04643 0.98125 0 2.85006 0.22234 2.21438 0.17275 0.80425 0.11651 0.62465 0.09047 55187.829491 0.000448 0.29790 0.04858 0.96774 0 2.87147 0.22449 2.21784 0.17337 0.85542 0.12242 0.66079 0.09457 55187.830411 0.000472 0.28488 0.04620 0.98160 0 2.82052 0.21522 2.17313 0.16583 0.80351 0.11499 0.61949 0.08866 55187.831236 0.000353 0.33960 0.05605 0.99180 0 3.10893 0.26008 2.42351 0.20274 1.05579 0.15020 0.82349 0.11715 55187.832150 0.000561 0.22565 0.03543 0.97938 0 2.97216 0.20261 2.33273 0.15900 0.67066 0.09485 0.52719 0.07456 55187.833383 0.000671 0.17093 0.02619 0.97414 0 3.31009 0.19495 2.59015 0.15255 0.56581 0.08002 0.44322 0.06268 55187.834636 0.000582 0.23291 0.03704 0.98507 0 2.73827 0.18992 2.14816 0.14899 0.63777 0.09127 0.50060 0.07164 55187.835753 0.000535 0.21170 0.03352 0.97838 0 3.27207 0.21565 2.57334 0.16960 0.69271 0.09973 0.54472 0.07842 55187.836916 0.000628 0.20442 0.03214 0.98157 0 2.90997 0.18917 2.27531 0.14789 0.59486 0.08514 0.46535 0.06660 55187.838557 0.001013 0.24277 0.02819 0.94857 0 2.92815 0.14850 2.30722 0.11700 0.71087 0.07426 0.56090 0.05859
