Improve the classification algorithm if necessary.  </p> PIPE2D-985 Validate classification accuracy by using external catalogs Task Normal In Review Unresolved ishigaki ishigaki Sun, 20 Feb 2022 20:42:01 +0000 Wed, 20 Dec 2023 06:32:47 +0000 0 2 <p>The classification accuracy has been validated by the SDSS/SEGUE catalog. <br/> The predicted parameters by the method using brutus have a mean accuracy of ΔTeff=102±243<span class="error">&#91;K&#93;</span> and logg=0.4±0.4<span class="error">&#91;dex&#93;</span>. An actual performance should be verified during upcoming engineering observations.</p> <p>Is there any known systematic error in the SEGUE stellar parameters?  Also, uncertainties are a function of magnitudes and I suspect SEGUE stars are brighter than typical standard stars for PFS.  How much brighter?  We will measure the accuracy with engineering data, but please provide a few more details before closing this ticket.</p> Blocks PIPE2D-362 PIPE2D-984 PIPE2D-982 PIPE2D-983 Development Epic Link PIPE2D-1277 Rank 0|zzst4n: Reviewers msyktnk
