In your ballistic analyses did you take into account the parameters you can glean from Chapman (1964). Understanding the re-entry angles and velocities of tektites at specific locations allows you to work backwards with the ballistics. There are a range of solutions and they set a limit on where the crater can be located.
Dear Aubrey, This unfortunately is not my expertise. But Tim Harris did some suborbital analysis calculations shown in the slide following that on Chapman. I have made only some basic ballistic assumptions in our GSA Special Paper 553 contribution.
The most accurate estimate in my opinion is ~43 ± 9 km (Glass & Koeberl, 2006). If in soft sediment there could be enlargement by slumping. Estimates have varied widely, but as Mizera mentions in relation to Bolaven, the crater should be significantly larger than Ries Crater.

A předpokládaná velikost toho asteroidu a velikost kráteru který následně vytvořil ?

Kráter je odhadován na 30-120 km (průměr), čemuž by odpovídal asteroid o průměru 2-3 km.
