Title: Return star array from StarDetector
Post by: dave_galera on 2020 January 15 05:32:58

I am trying to get relevant information using the following after executing starDetector

stars.position.x, stars.position.y, stars.radius, stars.flux, stars.size, stars.bkg etc.

The .position and .radius are returning values however .flux, .size and .bkg are undefined and I get the following return:

{"position":{},"radius":5}

Question, is it possible to get the .flux, .size and .bkg values?

Thanks in anticipation

OK so I know what I was doing wrong, I have sorted that problem and now I get:

{"position":{},"radius":4,"flux":0.01169074873905629}

But I still can't get .bkg using the following:

barycenters.push({
                  position: stars.pos,
                  radius: Math.max(3, Math.ceil(Math.sqrt(stars.size))),
                  flux: stars.flux,
                  bkg: stars.bkg
               });
