Sentinel1 image information

Where exactly can I find the timeline of Sentinel 1 interferometry images?

if you mean the temporal baseline, you can select a coregistered stack and then open the InSAR stack tool grafik (Tool > Windows > Radar > InSAR Stack)

This gives you a baseline chart

and a list with all image pairs of the stack

How do I create a single file coreigestered stack to be an input for the InSAR stack tool to plot this temportal/perpendicular baseline chart?
This is what I get when I try the following
Radar>>> Sentinel TOPS Coregisteration>> S-1 Back Geocoding
then adding all the split products together with the suggested master scene after the automated python2 project.conf process, so that all the input products are exactly the same IW and burst numbers
