NUMBER: 127 MODULE: artdata.mkobjects SYSTEM: V2.9 DATE: Mon Jul 2 11:41:14 MST 1990 FROM: valdes BUG: Objects which fall partially off the lower edges of the image (objects with centers near the (1,1) image origin) are shifted by 1 pixel to larger coordinates. STATUS: This bug is caused by incorrect rounding of negative numbers. The bug has been fixed. The workarounds are to either compensate for the error in the analysis or offset the coordinates to larger values (say by using the offset parameters) and make a larger image which can then be trimmed with IMCOPY. The tricky thing is knowing when the objects go off the edge since the full object size depends on seeing and the specified dynamic range. NUMBER: 241 MODULE: sarith, scopy SYSTEM: V2.10 DATE: Tue Apr 12 13:56:49 MST 1994 FROM: valdes BUG: If a spectrum is 'multispec' with more than 127 APID keywords the tasks will fail with a segmentation violation. This is due to a limit in a keyword template expansion step. The work around is to delete some of the keywords with: cl> heditapid1?? del+ Note that you can't delete them all since HEDIT has the same limit. The APID strings can be restored from an aperture identification file using SAPERTURES at a later time. STATUS: In V2.11 the limit on the number of keywords in a template expansion has been increased to 1024. NUMBER: 358 MODULE: dofibers, dohydra, doargus SYSTEM: V2.10-V2.10.2 DATE: Wed Jan 15 09:32:23 MST 1997 FROM: valdes BUG: When there are more than 127 fibers and the aperture identification file has titles for all the fibers these script tasks will fail either with a segmentation violation or the error 'Too many field names in image header field name template'. This is caused by calls to SCOPY and SARITH in the scripts which trigger the previously recorded Bug #241. The only work around is to not use aperture titles. At the end of the processing one may associate titles with the apertures using SAPERTURES. STATUS: Fixed in version 2.10.3.
