Due to a bug in exprEval in tcl, secTarget was set to 
-2147483647 (= 0x80000001) instead of the intended
-2147483648 (= 0x80000000) in the original
plPlugMapT and plPlugMapP files. To fix this, the original
files were moved to the "OLD" directory, then "fixtarg.scr"
was run, which simply used sed to make the needed change
in secTarget in the plPlugMap* files.

Also the 0x20 LRG bit was not set for the Cut II LRGs.
This was also done by "fixtarg.scr", which changed
-2080374784 (= 0x84000000) to -2080374752 (= 0x84000020).

The revised plPlugMapP files were then used to replace the
old files, in the sdssdp4 anonymous ftp area

  /sxftp/plates/dr2002.05.3/PlugMapP

as well as on plate-mapper.apo.nmsu.edu under the direcotry

  /ide_disk/plates/plate-1021-1037
