Description

Dear all

I am trying to process radargram data acquired by Kaguya LRS instrument which are in PDS format.
I am able to convert the .img file into a .cub and get the image object. However I am also interested in getting the auxiliary data, which are arranged in different columns. Is there anyway to dump these columns to a text file like the utility "tabledump" in isis.

below given is the output metadata obtained using the following command:

catoriglab FROM=LRS_SWH_RV20_20071227130958.img TO=ggg123.txt

Here is the output:(sorry for long text, I couldnt attach text files)

Object = IsisCube

End

Any tip on this will be of great help.

Thanks and regards
