how to get X,Y PEAK values?

[plaszczy]

hi, there used to be the XPEAK,YPEAK values in SE2. However I can't find it in ShapeParameters. Is is available somewhere?

[mkuemmel]

The property is called PeakValue in SE++. Note that: sourcextractor++ --list-output-properties lists all available properties. This one is quite explicit, no?

[plaszczy]

yes I tried it. but it gives only the Peak value not the position of the peak. Can we deduce it from other properties?

[mkuemmel]

What you can do is the following:

• generate the background model image;
• generate the partition check image;
• for each object:
  • take the partition area;
  • search in detection-background image for the peak flux value;
  • get the x/y value;

Not that sure whether this counts as "deduce from other properties", though. If you really think it make sense to have the x.y values make a request and we will discuss it. The implementation is not that difficult for the detection image.

I think it used to be there in SE2, could be added to the PeakValue property. I'll make a request, thanks.

[plaszczy]

not sure how to make a request..on the PR page I can't create one (it goes to some code comparison page...)

[mkuemmel]

Well, just open a new ticket on github.

But in the end everyone got this conversation, so the situation is clear.

[plaszczy]

OK thank you

If I understand correctly, shoudl'nt have closed this thread,

@plaszczy v0.17 is out since two weeks. Could you confirm that this measurement is there? Can we close the issue?
