Tomasz, Jayson,
What about timeframe settings? I can see that I can have several
addtocomposite() calls in one scan, but it looks like to run a 78-min
composite the periodicity would need to be set to 78 mins in the scan
settings, and to run a 13-min composite it would need to be set to 13
mins, and so on. That looks like several scans to me. Is that right
or have I missed something?
Thanks
Phil
