I seem to recall that you've posted a similar question before. Therefore you might find this link useful:
http://www.subway.co.uk/assets/pdf/Subway-Nutritional-Values-2012.pdf
It shows how many calories there are in each of Subway's 6" subs. You can then use that as a guide for the baguettes you're eating.
Chicken Temptation is shown as 406 KCal but your baguette looks as if it might be a bit bigger, so perhaps 600 kCal might be a reasonable guess?
