I monitor guiding performance on the PHD Graph module, but I have to switch back to the PHD window to see the RMS error. The graph module takes up a lot of real estate on my smaller laptop screen (I only have room for 2 modules per side), but the graph only uses a small portion of that.
A display of the RA, Dec, and Total RMS error under the graph would be awesome. Also maybe the SNR and/or star mass?
On a similar note, would it be possible or practical to calculate the average RMS error for each exposure duration, and if so write it to the fits header? - Does anyone have any comments on whether this would be useful to aid in image grading?
