S1 TOPS ESD Coregistrations fails to complete

Hi all,

I am finding that when I run S1 TOPS ESD coregistration with images collected before Dec 2015, the process fails to complete. I am using version 3.0.3 of the toolbox and running the coregistration using Radar-> Coregistration->S1 TOPS Coregistration->S1 TOPS coregistrations with ESD. The progress bar reaches 100%, but then fails to say “Process completed in x seconds…” and I am not able to do any further processing. I have also tried to run the coregistration using each process individually (i.e. TOPSAR split, apply orbit files, back geocoding etc) and it fails to complete at the backgeocoding stage.

An example pair where this is a problem is:
S1A_IW_SLC__1SSV_20151107T105923_20151107T105947_008497_00C059_4469.zip
S1A_IW_SLC__1SSV_20151201T105917_20151201T105941_008847_00CA32_9DEF.zip

However it is not a problem for pair:
S1A_IW_SLC__1SSV_20151201T105917_20151201T105941_008847_00CA32_9DEF.zip
S1A_IW_SLC__1SSV_20151225T105916_20151225T105940_009197_00D407_D4AC.zip
or any other pair after Dec 2015, so I do not think it is linked to my system setup.

Thanks
Amy

Further to my last post, for the image pair:

S1A_IW_SLC__1SSV_20151107T105923_20151107T105947_008497_00C059_4469.zip
S1A_IW_SLC__1SSV_20151201T105917_20151201T105941_008847_00CA32_9DEF.zip

the second subswath IW2 (that I want to use) will not coregister as described before. I can however coregister bursts 2-7 for IW2, followed by interferogram formation and S1 deburst, but when I perform Topographic Phase Removal the process fails to finish. This was not a problem with previous versions of the software and is not a problem with image pairs collected in 2016. I am now running version 4.0.0 of the toolbox. @lveci or @junlu are you able to have a look at this example pair please?
