	We will consider all the SMO as consistently processed Observational Sites. We need to confirm our processing of the SCEDC event data, and compare our signal processing between data sets for some of the overlapping data sites where we have both SMO data and SCEDC data.

-In these merged data sets, we will manage the observational data separately until we have confirmed the processes of each data set. The SMO data will be in the processed V2 cosmos format.
+This merged data set, we will require we manage two types of observational data. The SMO data will be in the processed V2 cosmos format. The SCECDC data will be in SEED format, probably unfiltered and in counts. SCEDC data in Counts will need to be converted to acceleration using a gain factor in a metadata file posted on the data download site.
