Output a list of filenames with image weights?

Marsha Ann Wilcox

I'm wondering if there is a relatively easy way to output a list of images and their assigned weights.  I've been using a heuristic approach for including images in the final integration (e.g. rejection =0.50).  

I'd like to take a look at a graph of the weights in order to consider an empirical approach based on the distribution of actual weights. 

Thanks for your thoughts on this,

Marsha,

The way to do this is to measure your frames with SubFrameSelector. It shows you the weights of each image (each type of method). You can also output these values to a CSV file and make your own graphs as I did in my weighting videos (I hope you watched them).

But the answer to your question is to use SubFrameSelector. 

Two caveats:

1. By outputting the values, you can show relative weights (meaning a reference is "1" and the other frames are given their relative value). I do not believe SFS does this by default. 

2. PSF Scale SNR weights are not available to you until Local Normalization is run on the data. Please see my videos to understand why this is.

Thanks, Adam.

I understand why the PSF Scale SNR weights aren't available until after LN.  NSG used to include them in the output filenames.

Feeling a little sheepish - I should have thought about SFS myself.  I have seen your videos.

Thanks again for your kind response.
