UCAC4, edbs with Mac, Xephem 3.7.7


 

Using Xephem 3.7.7 on Mac,? OS 10.9.5 (recent update). ? ? Have? been using UCAC* in last several versions of XEphem, usually works o.k.,? but currently doesn't.

All of the folders auxil, catalogs, help, etc. are in ~/Library/XEphem,? and my home directory has the .xephem directory containing the file XEphem, first line:


XEphem.ShareDir: /Users/ameyer/Library/XEphem/


What's weird to me is that I have GSC 2.201 in the catalogs folder there, and Xephem finds that catalog o.k., using the path given in the Field Stars setup panel? (/Users/ameyer/Library/XEphem/catalogs/GSC2201.?? I have the full stock set of .edbs, and several custom ones, in Library/XEphem.? Any .edb file that I? "demote" into the catalogs folder disappears from the Data-FIles list of .edbs.??
So at least I can use the .edbs by not doing that, although they used to be available from within the catalogs folder.? That would be at least aesthetically better.?


As for UCAC4, I've tried it both ways, I've tried naming the folder UCAC4 instead of UCAC.? In each case modified the path in the Field Stars setup panel accordingly, re-started Xephem, zoomed in to ~1 degree, but still no go.??

If the path in the Field Stars setup panel is not right, the message is something like "Can not find u2index.da or u3index.unf or u4index.unf",? as expected, since they are needed first to select the data.? When the path is right, the error message changes to just "UCAC:? Error reading UCAC data near 15:30? 26:00",? with the coordinate string matching the current FOV center.?? So apparently Xephem is using the path, and finding an index file to use (presumably u4index.unf), but somehow can't read the data.?? I've tried it with "u4index.unf" both inside the u4i folder, and outside it, just in the UCAC folder.? Same error message either way.

I seem to recall a couple versions of Mac OS and/or of XEphem back when Elwood said that the catalogs, edbs, etc.? should be in Library/XEphem, and adopted that.?? But maybe it still shouldn't matter, as long as the ShareDir path in? ~/.xephem/XEphem? is correct, as the install instructions say.?? So wondering with my recent OS update if this is due to some "feature" of OS 10.9.5.???

I've run out of dumb guesses, and it probably is something trivial in the setup, so hoping for a silver bullet from anyone out there.?
