/* ** ** 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 56012.228489 0.000501 0.15562 0.01206 1.00000 0 15.90784 0.45035 14.66200 0.41508 2.47558 0.17857 2.28250 0.16462 56012.229783 0.000793 0.14900 0.00931 0.99710 0 16.50710 0.36949 14.99458 0.33563 2.45954 0.14352 2.23274 0.13029 56012.288852 0.000394 0.18411 0.01468 0.99265 0 17.11213 0.53056 15.70481 0.48689 3.15044 0.23149 2.88948 0.21229 56012.289717 0.000472 0.14579 0.01143 0.99387 0 17.86818 0.49044 16.51630 0.45333 2.60502 0.19139 2.40790 0.17691 56012.290690 0.000501 0.15414 0.01191 0.97688 0 16.45835 0.45906 15.18003 0.42341 2.53683 0.18283 2.33949 0.16861 56012.291604 0.000414 0.18641 0.01435 1.00000 0 16.44387 0.50670 15.11403 0.46568 3.06531 0.21622 2.81587 0.19862 56012.292481 0.000463 0.16448 0.01294 1.00000 0 16.17230 0.47478 14.88702 0.43702 2.65996 0.19415 2.44903 0.17878 56012.293363 0.000420 0.18589 0.01437 0.98621 0 16.31475 0.49890 15.08165 0.46120 3.03280 0.21527 2.80353 0.19900 56012.294263 0.000480 0.15741 0.01209 0.98193 0 17.04854 0.48171 15.58065 0.44024 2.68357 0.19170 2.44872 0.17492 56012.295256 0.000512 0.18278 0.01263 0.99435 0 16.92522 0.46008 15.64591 0.42530 3.09356 0.19645 2.85974 0.18160
