metadata missing while subset using latlon on alosStack products #1256
Description
Description of the problem
I want to subset ALOS data generated from ISCE2 2.6.3 using latitude and longitude information.
A file, data.rsc, has been successfully generated in the reference date directory. I also use them in the same environment.
However, it gives an error and asks for information such as 'EARTH_RADIUS' as described below.
** Command **
smallbaselineApp.py subset_alosStack.txt --dostep load_data
