/* ** ** 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 59311.032091 0.000813 0.11329 0.00854 0.99288 0 13.81765 0.33362 12.66685 0.30580 1.56536 0.11180 1.43450 0.10247 59311.033717 0.000813 0.11073 0.00833 0.97865 0 14.12966 0.33278 13.06229 0.30764 1.56460 0.11176 1.44619 0.10331 59311.035297 0.000767 0.11734 0.00890 0.98491 0 14.01264 0.34169 12.93575 0.31543 1.64428 0.11805 1.51808 0.10899 59311.036790 0.000726 0.12142 0.00925 0.99203 0 14.18354 0.35438 13.12205 0.32786 1.72221 0.12396 1.59333 0.11469 59311.038312 0.000796 0.11004 0.00848 0.98182 0 14.24195 0.33957 13.14636 0.31345 1.56715 0.11485 1.44551 0.10593 59311.040370 0.001262 0.10909 0.00665 0.99541 0 14.20522 0.26884 13.14248 0.24873 1.54965 0.08973 1.43371 0.08302
