(10*(1-(FWHM-2.528)/(2.528-4.482)) + 10*(1-(Eccentricity-0.497)/(0.847-0.497)) + 30*(SNRWeight-1.1167)/(1.1479-1.1167)) + 50

You have inverted the FWHM value in your term. It should be (FWHM-2.528)/(4.482-2.528). I notied this because I just made the same mistake.

Wow - what a bonehead - here I am typing all this detail... Thanks!

Hey Mike,
I think in some cases the old expressions may be used, but in this case I think you'll benefit from reading the tooltips on the expression inputs. For example, you can replace a lot of your constant numbers with smart parameters like FWHMMin, EccentricityMax, and so on.

Sounds great. Where can I find the expression inputs? I've looked and unable to find. Thanks for all the help!

Sorry, I meant 'expression inputs' as the text area inside the SS where you are typing the Weighting or Approval Expressions. Hover over them for a little bit and you'll get a large tooltip explaining the things you can type into them. I think that most things in the SS will have these.

'Inputs' is a common term for a UI developer to say something that receives user information, like a box to type in text, or a checkbox, or a file browser icon.

Got it. So if I understand the documentation the formula would read:
(10*(1-(FWHM-FWHMmin)/(FWHMmax-FWHMmin)) + 10*(1-(Eccentricity-Eccentricitymin)/(Eccentricitymax-Eccentricitymin)) + 30*(SNRWeight-SNRWeightmin)/(SNRWeightmax-SNRWeightmin)) + 50

Btw I love the fact that the data points are cached. I forgot to identify the best weighted image among my LRGB files - what a breeze with that feature!

Where can I get the latest version for windows?

The changes that I've listed in this thread are in that link. The *latest* version will come with the next version of PixInsight.

great thanks. I looked on github and it looked like the date was september, but i'll download the latest, and await the PI update

I think that's because I setup the release for Linux then, and simply updated it with the Windows build after I stopped procrastinating. It wasn't a new release and it doesn't show an "edited" timestamp.

A person mentioned in a related post that some Weighting expressions are built in. I’ve looked all over SFS and can’t find them. Is that possibly not the case, or where might they be located?

[cameronleger]

If you're thinking of whole preset Weighting Expressions, then no that's not the case. Maybe they were trying to talk about the "variables" that are pre-defined for use in the Weighting Expression, such as "EccentricitySigma" or "FHWMMax", which would be replaced with the values of the Eccentricity in Sigma units of the whole set or the maximum FHWM value of the whole set, for example. Hover over the expression text boxes for a tooltip that describes them.

Once you come up with one you like, if you save the instance as an icon on your workspace it will be there for you next time you open it.

I've just stumbled across this and it looks awesome but i've hit a brick wall here.

I downloaded the Windows version of the zip file from https://github.com/cameronleger/PCL/releases/tag/01.04.01.0001 but i'm not sure how to install/add this script to my PI.

Sorry for being thick.
