/* ** ** 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 57463.079642 0.000327 0.08734 0.01302 0.99115 0 11.50196 0.48344 10.12953 0.42573 1.00459 0.14367 0.88622 0.12674 57463.080388 0.000420 0.07346 0.01076 0.98621 0 10.78797 0.41370 9.54243 0.36593 0.79248 0.11208 0.70047 0.09906 57463.081115 0.000307 0.10056 0.01477 0.97170 0 11.10154 0.49166 9.86409 0.43686 1.11639 0.15633 0.99194 0.13890 57463.081803 0.000382 0.09973 0.01317 0.96212 0 11.27321 0.44438 9.97223 0.39308 1.12424 0.14165 0.99378 0.12520 57463.082506 0.000321 0.08962 0.01397 0.97297 0 11.20661 0.48477 9.90084 0.42823 1.00435 0.15035 0.88533 0.13251 57463.083319 0.000492 0.09497 0.01119 0.98235 0 11.54330 0.39604 10.25490 0.35184 1.09622 0.12363 0.97387 0.10983 57463.084121 0.000310 0.09920 0.01456 0.98131 0 11.05334 0.48748 9.81569 0.43290 1.09649 0.15354 0.97305 0.13625 57463.085018 0.000587 0.10182 0.01097 0.97044 0 10.94707 0.35500 9.66609 0.31344 1.11465 0.11455 0.98272 0.10099 57463.086013 0.000408 0.10798 0.01389 0.97163 0 10.29695 0.41082 9.14775 0.36497 1.11185 0.13594 0.98771 0.12077 57463.086731 0.000310 0.10143 0.01522 0.98131 0 10.56225 0.47869 9.33635 0.42314 1.07136 0.15321 0.94530 0.13519 57463.087362 0.000321 0.09662 0.01448 0.99099 0 10.69081 0.47356 9.43560 0.41796 1.03289 0.14783 0.91227 0.13059 57463.087998 0.000315 0.09404 0.01421 0.97248 0 11.23221 0.48919 9.86494 0.42963 1.05624 0.15280 0.92780 0.13419 57463.089187 0.000874 0.10532 0.00923 0.98344 0 10.58932 0.28491 9.37263 0.25217 1.11521 0.09307 0.98604 0.08229
