<div dir="ltr">Hi,<div><br></div><div>I am trying to use UVFLG to unflag a VLBA antenna which was falsely flagged during the observation [BM267A, 6 April 08, antenna HN, ellipsoid position</div><div>does not match, but doesn't affect data, according to operator log. It appears that UVFLG was recently modified [July 15] so there might be a new gremlim.</div>

<div> Note that the adverbs must match the flag or be</div><div> set to special "ignore this adverb" values.</div><div> Defaults are not applied for UFLG.</div>
<div><br></div><div>Perhaps one or more adverbs are not set to 'ignore this adverb', but I can't determine which one(s).</div><div>I also tried REASON '*', no luck. The PRTAB table says REASON = 'Ellipsoid posn error', which I also tried</div>
<div>without success - anten 5 is still flagged [as determined by, e.g., LISTR output]</div><div><br></div><div>Thanks</div><div><br></div><div>Robert</div></div></div></div>
