This folder contains data and information pertaining to the expendable CTDs. 1. The folder titled "XCTD Log" contains a single Excel file with a record of all launches, their positions, and other launch information. 2. The folder titled "XCTD RDF" contains the Raw Data Files (RDFs) from all of the successful launches. These can be read only using Sippican's Mk12 software. The numbers on the filenames reflect the probe sequence numbers. 3. For those of you who don't have the Mk12 software, we've prepared Export Data Files (EDFs) for every launch. These can be read on spreadsheets and many other programs. There are two folders of EDFs, one with the data presented in metric units ("EDF Metric") and one presented in English units ("EDF English"). As with the RDFs, the numbers on the filenames reflect the probe sequence numbers. Point of Contact for this data is Randy Ray at ASL.
