Using the search elset that I've made the mar.25 for liftoff at 01:21 UTC:

IGS 10 estimation                                        481 X 488 km

That looks to be the payload as mean motion is nearer gives a satfitting:

Its very forced (too much differential correction) but fits quite well:

Prefer to wait to the opinion of the experts. Made it just for fun.
