/* ** ** 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 55854.710225 0.000362 0.08776 0.02074 0.97600 0 4.73548 0.31259 3.72906 0.24600 0.41557 0.09431 0.32418 0.07356 55854.710960 0.000373 0.08481 0.02005 0.97674 0 4.56150 0.30350 3.65720 0.24330 0.38684 0.08777 0.31389 0.07122 55854.711814 0.000480 0.09194 0.01698 0.96988 0 5.28852 0.28324 4.32822 0.23181 0.48622 0.08595 0.39818 0.07039 55854.712720 0.000425 0.07361 0.01705 0.96599 0 4.69761 0.28368 3.83287 0.23146 0.34581 0.07732 0.28216 0.06309 55854.713541 0.000396 0.07494 0.01763 0.97810 0 4.82580 0.29916 3.93820 0.24414 0.36163 0.08206 0.29515 0.06697 55854.714265 0.000327 0.09125 0.02192 0.97345 0 4.76490 0.32555 3.88898 0.26571 0.43479 0.10013 0.35485 0.08172 55854.714942 0.000350 0.09636 0.02255 0.95868 0 4.39406 0.30389 3.58419 0.24788 0.42341 0.09468 0.34540 0.07723 55854.715720 0.000428 0.07263 0.01682 0.96622 0 4.72556 0.28500 3.86006 0.23281 0.34321 0.07674 0.28019 0.06265 55854.716493 0.000344 0.10254 0.02406 0.95798 0 4.20019 0.29853 3.42783 0.24364 0.43068 0.09630 0.35146 0.07859 55854.717176 0.000339 0.08741 0.02096 0.96581 0 4.83557 0.32376 3.95274 0.26465 0.42268 0.09733 0.34543 0.07955 55854.717821 0.000301 0.10793 0.02540 0.97115 0 4.50268 0.32982 3.67478 0.26918 0.48596 0.10866 0.39670 0.08870 55854.718483 0.000362 0.08809 0.02035 0.99200 0 4.65450 0.30907 3.80267 0.25251 0.41004 0.09073 0.33511 0.07415 55854.719294 0.000448 0.11020 0.02139 0.97419 0 4.38378 0.26668 3.58008 0.21779 0.48310 0.08906 0.39459 0.07275 55854.720613 0.000871 0.09099 0.01345 0.94684 0 4.82550 0.20139 3.93770 0.16434 0.43905 0.06228 0.35827 0.05082
