4.(F)/123, 5.(F)/123 and NAG 13

What were the tasks of these three Reconnaissance units in France?
Reconnaissance flights over the UK seem to me a bit difficult, considering the British air defense in 1943 and 1944 as well as the limited range of the Fw 190 and Bf 109.
Or did they perform other tasks such as patroling the coast and the ocean, intercepting Allied bombers and fighters,...

Thanks in advance and best regards
