20.2.2 /FILE

[ADVANCED\]FEATHER /FILE Combined HIGHRes LOWres [/REPROJECT]

Takes the data from files named HIGHres and LOWres and put the combined result in file named Combined. The default extension .lmv-sky.

Without the /FILE option, FEATHER takes HIGHres from the SKY buffer, LOWres from the Short Spacing buffer (SHORT, equal to SINGLE if it is a data cube, or derived by UV_SHORT if not), and put the result into an image variable named FEATHERED. The result can be written as any image by WRITE FEATHERED FileName.

Note: Currently, in all cases, the images reside in memory. A buffer mode for the /FILE option will be added later.
