Gitane like most French bike makers measured the frame size by the height of the seat tube Center to Top.
My first Gitanes had 60cm size frames: a 1972 Gitane Gran Sport, and a year later when I got serious about cycling, a NOS all Campy 1971 Super Corsa that I bought for $150 at a year end clearance sale at the shop where I worked part time.
Soon I realized that those frames were over an inch to big for me and I swapped the 60cm SC frame for a 57cm one at another Gitane dealer.
In 1975 I started dabbling into racing and switched to 54cm frames: seat up high and back, bars down and forward which was the fashion back then.
Just parted with one of my 54cm Gitane Super Corsa bikes, a low mileage 1969-70 all Campy that I've had since 2010 and only ridden a few time.
I'm riding mostly my 55cm - 56cm bikes so the 54cm ones are getting cut out of the herd.
BTW... Sacrilege! I traded the SC for a late 60's ITALIAN bike...
