codespell seems to be right on the ball:

@stes -- ping to review this. @bendichter I pushed the fix for the typo

[yarikoptic]

@bendichter would you be kind to rebase it so we hopefully pacify codespell -- if still red, needs fixing of typos then.

ping @stes on a request to review. If not available - any other review candidate @bendichter ?

[yarikoptic]

ping @bendichter on quick above. Let me know if need assistance.

Ah, apologies --- I somehow missed the notification. I will give the PR a look in the coming days @yarikoptic @bendichter .
