Sentinel 1 corrections order


I am working with a Sentinel 1 image of an area. I wish to work on a subset of the image. Should I take the subset first and then apply the corrections or should I first apply the corrections and then take the subset?

I do not think the order plays important role. We usually subsetting the image to make the processing faster. So, if you think that the processing time for your SENTINEL-1 image it too long, you can first subset the image and then apply the processing steps.
