Warnings and Error With DAOFIND and PHOT

Robert Moore wrote on Mar 18, 2010

I've been using PHOT for a bit and getting warnings of the following:

WARNING: Graphics overlay not available for display device
WARNING: Image <filename> Keyword: not found

The warnings don't seem to hinder the working of PHOT (that I've noticed), but no one else seems to be able to figure out why I'm even getting them.

Recently though I've started trying to use DAOFIND to try and get beyond working on one image at a time, and it's giving me an error of:

ERROR: Cannot open device (node!imtool,,512,512)
daofind()

Again, no one I'm working with seems able to determine why I'm getting this error.

If anyone can offer suggestions or help, they'd be greatly appreciated.

WARNING: Graphics overlay not available for display device

This is normal (and annoying), graphics overlays were never implemented.

WARNING: Image <filename> Keyword: not found

Check the help page for required keywords. This may not be fatal, but indicates a missing e.g. airmass, filter, exposure time, etc keyword.

ERROR: Cannot open device (node!imtool,,512,512)
daofind() 

This means there is no DS9 or XImtool running and you are trying to use the image display. You can set the task 'display' parameter to be 'stdgraph' if you want to use the task with an e.g. CONTOUR plot (see the help examples). Otherwise, start a display server before using the task.
