/* ** ** Swift/XRT hardness ratio for Mrk 421. ** 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 55215.328619 0.000550 0.32254 0.01198 1.00000 0 43.00163 0.78492 32.30883 0.58959 13.86979 0.44844 10.41328 0.33657 55215.329290 0.000122 0.26712 0.02185 1.00000 0 44.79074 1.67947 35.25567 1.32196 11.96447 0.86996 9.41798 0.68484 55215.329554 0.000142 0.27661 0.02075 1.00000 0 44.70332 1.55052 35.12256 1.21822 12.36534 0.82247 9.71527 0.64618 55215.329860 0.000165 0.30720 0.02152 1.00000 0 40.55594 1.37428 31.76348 1.07636 12.45893 0.76393 9.75757 0.59831 55215.330144 0.000119 0.28581 0.02350 1.00000 0 43.07719 1.67666 33.74205 1.31332 12.31186 0.89168 9.64331 0.69842 55215.330749 0.000486 0.36563 0.01377 1.00000 0 41.13023 0.80070 32.22744 0.62738 15.03850 0.48463 11.78564 0.37980 55215.331773 0.000538 0.31482 0.01174 1.00000 0 42.64677 0.77455 33.53050 0.60897 13.42602 0.43752 10.55588 0.34400 55215.332838 0.000527 0.32679 0.01213 1.00000 0 42.37698 0.78040 33.25934 0.61249 13.84843 0.44651 10.86804 0.35041 55215.333532 0.000168 0.29190 0.02035 1.00000 0 42.03095 1.38567 33.11358 1.09167 12.26888 0.75368 9.66461 0.59371 55215.333819 0.000119 0.28275 0.02332 1.00000 0 43.43833 1.68274 34.30644 1.32897 12.28220 0.89429 9.70093 0.70634 55215.334446 0.000509 0.35116 0.01330 0.99432 0 40.54703 0.77518 31.88852 0.60964 14.23833 0.46561 11.19958 0.36624 55215.335074 0.000119 0.28412 0.02394 1.00000 0 42.10879 1.65210 33.13655 1.30005 11.96400 0.89218 9.41653 0.70237 55215.335731 0.000538 0.31448 0.01166 1.00000 0 42.82771 0.77551 33.69099 0.61006 13.46837 0.43588 10.59317 0.34282 55215.336805 0.000535 0.31525 0.01178 1.00000 0 42.79139 0.77778 33.62368 0.61115 13.48980 0.44057 10.60405 0.34631 55215.337459 0.000119 0.26803 0.02302 1.00000 0 43.74757 1.69681 34.47016 1.33696 11.72552 0.89856 9.23861 0.70798 55215.338576 0.000998 0.33680 0.00900 0.99710 0 42.20054 0.56400 33.27055 0.44464 14.21313 0.32911 11.20551 0.25946
