Here's some more info for those of you who are trying to 'make a plate' (or more) with some extra star/cluster fields for Monday Nov. 26. We'd like to have these special plate files for this round all in by 5pm CST Nov 26,2001. Brian Yanny will be available Monday to help verify that your plPlugMapT-XXXX.par file will make a 'valid plate', without collisions, with proper sampling of objects, sky, guide and other fibers. Please e-mail yanny@fnal.gov with the location of a plPlugMapT file(s) that you want validated. We will assign unique tileIds and Plate# id's Monday, for working purposes, you can use tileids 99XX and plateids 9XX, where XX is an integer. You can run the 'plate making process' yourself if you like, and if you have a login on fnal computers sdssdp2.fnal.gov (or sdssdp3.fnal.gov). For obscure reasons, the 'plate' code, currently only runs on OSF1 machines. I have made a 'sample special plate' (a plate full of magnitude g'=19-20.5 F dwarf stars at RA~5hours) and validated it thru the plate process. All the files used, are in: sdssdp2.fnal.gov:/home/s1/yanny/oneplate And you may look there for examples of how to do it. You first make a plPlugMapT-XXXX.par file.
