Using "Authority Servers" (directory authorities) as Entry Nodes?

[judaiko judaiko]

Nodes: dizum, Tonga, dannenberg, maatuska are identified as being
"Authority Servers" on https://torstatus.blutmagie.de

I set the following in my torrc file:

EntryNodes dizum, Tonga, dannenberg, maatuska
StrictEntryNodes 1

Is my anonymity broken as the above nodes are "Authority Servers",
therefore they can log and identify the flow of traffic, mapping
destination and sources?
