I have 5 SLCs:
After loading the images, I split each of them as I’m only interested in subswath 1 (IW1) and bursts 8-9. I then apply orbit file to precise orbit to each of the split products. Then I go to co-reg the 5 images using S1 TOPS backgeocoding (placing my desired master at the top of the list) - I want the deramp/demod so I can apply ESD later since I have multiple bursts in each SLC image. When I go click the deramp/demod option it complains and gives the noted error ("… **already contains a band with the name ‘derampDemodPhase…").
Then I thought it could an issues related to applying the split before the orbit file step. So I repeated the procedure applying the orbit file step prior to the TOPS split operation - same issue when I go to coreg the images.
Lastly, when you repeat the above steps for a 2 image stack (as opposed to 5 images), things work just fine. The issue with the demod/deramp option toggled on doesn’t throw off the error.
