Very excited to try the new beta on my large Ha-O3 integration of the Veil with FLI KL4040 camera. Running it now but could not select the Local Normailzation Correction box. Does this depend on other settings?

Hi,

On my installation if the filter drop-down box is set to 'no rejection' then the select normalisation rejection check-box is inoperable. 

If any other option in the filter rejection drop-down is selected then the check-box becomes operable.

Probably an element of redundancy here because if 'no rejection' is an option what is the value of the check-box?

As you can see there is now a new weights option, which is set to "Auto". This will take care of these settings automatically on the basis of your data. If you still want to adjust it yourself (I would first test the auto setting), you can change the weights to e.g. median.

Thanks for letting us know, Mabula will have a look at this asap.

Hi @whixson & @mestutters & @vincent-mod,

If the integration mode is set to automatic it will control:

  • average or median integration
  • choose equal or quality weights (equal is preferred choice with little frames to stack for noise/Signal to Noise characteristic reasons)
  • enable/disable outlier rejection
  • choose the outlier rejection settings if enabled
  • enable/disable local normalization rejection when outlier rejection is enabled.

So when you set the integration mode to either average/median: you can control the outlier rejection settings yourself including local normalization correction.

And off course, if you set it to no rejection, the local normalization rejection selectbox is turned off naturally as an option, because if you would be able to turn it on, it would do nothing. That selectbox only applies when an outlier rejection filter is used...

Probably an element of redundancy here because if 'no rejection' is an option what is the value of the check-box?

Exactly 😉

Hope this clarifies the new automatic integration setting.

Mabula

Thanks! So choosing automatic integration kind of manages everything else?

It does yes, apart from the things you can still select.

Hi Wayne @whixson, indeed 😉

I have implemented this, because it should greatly improve usability of APP for many users, especially in the multi-channel/session modes where you will have integrations of different sizes and which would warrent different settings like median/average and the outlier rejection settings.

Thanks Vincent, Mabula!

Sounds like a great addition. Simplified and probably makes better decisions than I would.
