                               Week: 62


Tom Folkers:
     1. Installed Xview3 that's needed for databrowse. I was able to 
        get databrowse to compile and link but crashes when you invoke 
        it. I have asked Lori to look into these crashes.
     2. I unified the passwd and userID's files on all of our Linux 
        computers. This was necessary for SCCS to work properly. 
     3. Working on catalog tool. Making changes to reflect HHT 
        parameters. i.e. wrap and limits. Also to draw slew paths 
        while acquiring new sources.

Tom Sargent:
     1. Revised the sun proximity checking software to make it state 
        driven. That makes it easier to get useful warning and error 
        messages out of it.  I also realized that the code does not 
        take solar motion (the sidereal motion) into account when 
        computing a path. So for some paths taking a few minutes to 
        complete, the sun can move appreciably during the move. 
     2. Found 2 typos in the sun avoidance path code. It seems to be 
        pretty solid now.
     3. Wrote a program to compare refraction computed by the NRAO 
        algorithm and the SMT algorithm.

Pete Hubbard:
     1. Looking for power connectors that are used for amplifier power 
        modules in encoder chassis at the SMT. The existing ones have 
        horizontal pins and the new have vertical pins that are not 
        compatible. Also looking for linear supplies that operate on 
        117 V.
     2. Comparing different logic product types that will be able to 
        drive the counters used in the DBE cards. The old 74L157 chips 
        are not available.

Lori Warner:
     1. home/corona/cactus/dataserv/databrowse was examined for 
        segmentation fault. dl-lookup.c is missing from the system and 
        is needed. (system file) This may be due to the  Sun to Linux 
        conversion.
     2. Filled out accident report forms.
     3. Tour of hot, spinning, mirror with Dr. Hill.

Dave Ashby:
     1. No Report.
