+## note that this definition is inconsistent with the definition in
+## pmModules/src/objects/pmSourceIO_CMF.c.in.  The version in
+## pmSourceIO*.c creates a table with data not properly aligned with
+## the 8-byte boundaries. The structure defined by libautocode does
+## this, but has a different order of elements (and adds padding2 to
+## fix things). We have generated may files with PS1_SV1 as is, so
+## I'll leave it. But in future a PS1_SV2 should be forced to match
+## libautocode. Note that addstar knows to detect the alternate
+## version of PS1_SV1 and correctly interpret its fields.
