Error in Java heap space

“Java heap space” indicates insufficient memory. The S1 TOPS Coregistration is a chain of multiple separate operators. RAM is often not sufficient to execute all steps in sequence, especially when you select many bursts in the Split operator. I recommend to execute the steps separately, especially reduce the number of bursts as much as possible and make sure that you only use VV polarization.
