Also used as an estimate of the uncertainty in some tasks. Null value: none. <= 0 => false, > 0 => true. or 0 => task-dependent default Verbs: CHKNAME.....Checks existence of data set or image by name adverbs EGETNAME....Gets INNAME et al., setting ERROR true on empty slot. IMVAL.......Does cubic interpolation of image value; returns ERROR true if fit failed. MAXFIT......Finds coordinates and value of an image extremum; returns ERROR true if fit failed. QIMVAL......Does cubic interpolation of image value quietly; returns ERROR true if fit failed. Procedures: TVFLUX......Displays coordinates and values selected with the TV cursor; sets ERROR true if cubic interpolation fails. TVMAXFIT....Displays fit pixel positions and intensity at maxima on TV; returns ERROR true if MAXFIT fails on a position. Tasks: BSMAP.......Images weak sources with closure phases. ERROR is the error per unit weight in Jy. ----------------------------------------------------------------
