[enhancement] Select Y/X & tilt using a pre-existing log/settings file

[mconsidine]

If I do a partial scan of the solar disc - for example, starting in the middle and sweep to a limb - the image reconstruction will fail (in that it is wildly distorted) because the routines do not have enough info about the size of the solar disc. In the case where there is no limb at all visible, there is literally no information about the scale and parameters of the disc.

This can be overcome by inputting a Y/X ratio and a tilt. Using a prior successful sweep and assuming nothing else has changed, one can use the data from that successful run and then get a good reconstruction.

If possible, it would be useful to be able to have a dialog box that allowed one to select a log file from which to automatically read in this data. And if it could then be persistent, one could continue with partial scans that had no limb info.

So the workflow would be:

• start the session with a "successful" scan/sweep reconstruction
• using that ratio and tilt data continue doing "partial" sweeps of active regions only, with no limb info available and no need to interrupt the acquisition process

In this way, one could be monitoring a region, taking images for a movie, etc without having to stop and input data. This would dovetail well with the "live" mode.

Perhaps this only makes sense for high resolution setups (e.g. Stellafane, nominally), but may be a useful addition otherwise. I could image one monitoring an active region over an extended period and capturing a flare if one occurred.

I see the point now. Another thing could be to read the polynomial function (similar to what Valerie calls "freeline").
