Title: Help with a bad pixel/column on STL-11000M
Post by: logieberra on 2020 January 20 01:47:59

Hi,

I have a very stubborn bad column at the bottom right of my chip. See attached.

After running the batch-pre-processing script it is the only defect that remains. I just can't seem to get rid of it in PI.

A colleague put me on to CCDStack2 which works and does remove it via their "repair bad pixels/columns" tool, but I already own a copy of PI and would prefer to give it a good go before making the jump.

The data is available at this Dropbox link:  https://www.dropbox.com/sh/hdbzk198tzwnz17/AAD7tY44r30z5x1B7l96wKtQa?dl=0

I would be most grateful if someone would give this a crack and confirm what tool I might use in PI and recommended settings.

A big thank you in advance to that very kind person!

Logie

Use the pattern subtraction scripts in the latest PixInsight version

Use cosmeticCorrection on linear images after calibration.

See the third post here https://pixinsight.com/forum/index.php?topic=13954.msg84033#msg84033 for reasons why it may be better not to use cosmetic correction
