October 28,2009: Updated ETCs
The Exposure Time Calculators (ETCs) have been updated to include the latest throughput information available
from SMOV. In some cases, these updates can lead to different exposure time estimates than those provided by
earlier versions of the ETCs, so observers are encouraged to use the latest ETCs (v18.0) when preparing their MCTP
proposals.
