Problem in Downloading ECMWF ERA5 reanalysis data

Hi I am Hamza. I am newbie and working on SENET plugin. I have processed Sentinel-2 and Sentinel-3 data successfully. Now I want to download ECMWF Era 5 reanalysis data using snap SENET operator. But I am unable to understand to put Area of Interest (N/W/S/E). I don’t know how to calculate these from the Sharpen LST band and put it here. Can anyone explain it to me clearly, so that i can do it. I am attaching an image as well so that you can get it easily what I am trying to say.
Thanking You in Advance.
