I fell into this trap last week! Very often the wrong FIS frequency!

Yes Tim the coordinates of the whole FIC are correct, but there is a NOTAM A6542/23 :
LIBB LIMM LIRR
Periodo (UTC): 11/09/23 11:18 - 09/12/23 23:59 (stimato)

ROMA ACC AREA.
ROMA FIC FREQ WITHIN AREA DESCRIBED IN NOTE (10) COLUMN RMK:
- FREQ 125.750MHZ NOT AVAILABLE SOUTH OF LINE JOINING POINTS
420301N0111745E 421500N0112149E AND 421500N0134059E
- FREQ 119.075MHZ NOT AVAILABLE NORTH OF LINE JOINING POINTS
420301N0111745E 421500N0112149E AND 421500N0134059E
REF AIP ENR 2.1.1.2-3/4

that depict how to contact the FIS if you are north or south of this line dividing the FIC into 2 areas:  south of this line pilots should use the freq 119.075, and north 126.750,  so why not draw this LINE on your map and specify the two frequencies to be used on the flight information as per Note (10) column ?
