the frequency of 2c not plan to take eb1

Not misplaced. Most satellites located at 19.2, 23.5 and 28.2 are interchangeable as back up system and do have similar footprints.
That's correct, but it doesn't shift parallel but it somewhat heals over.
Well, the lower half of 2A but oddly they moved most of 2A's transponders out of reach of 2C when 2E arrived.So according to the fact sheet it could replace 2A?
I've attached some footprints of 2C at 28.2E from 2009.Hence my question of whether the footprint image is for 2C at 19.2 or 28.2?
Yep, you just need to see some of the current footprints at 31.5E to see how they can reorient the old beams to suit that position better.The footprint does have to point 9degrees further over because the satellite moves 9 degrees. But it does happen when the satellite is at test location because the satellite is tested with the same geocentric orientation.

Doesn't it depend where they want to point to beams? Tilting the beam north/south/east/west.Doesn't it depend on the satellite? Here is a picture of 1N's footprint when it was at 28.2 and it's quite a bit off, as seen by mislocation of Canary spot and shape of Italy. http://robssatellitetv.com/wp-content/uploads/2014/02/astra-1n_pan_european_ku_band_beam2_L.jpg
I wouldn't take too much notice of the SES site, according to that 1N now has just one European beam (ex PE2)...Also, according to SES website http://www.ses.com/4628719/astra-2c , 2C has one pan European beam, not north / south. Maybe they are just showing the south beam?

They are not steerable in the true sense, but look at the beams of the old birds at 31.5E to see how fixed footprints can be manipulated.I don't think the Astra satellites are designed with steering options on the European beams. And why would they? Extra costs and more to go wrong for very little benefit.
