R indicates a rectrice (tail feather), with numbers indicating feathers (of 6) from the centre. P indicates a primary feather, S indicates a secondary feather, and numbering counts from the primary/secondary boundary (thus, given there are 10 visible primaries in an adult pigeon wing, P8 is the third visible primary from the wing tip).
S3* indicates the synchronising accelerometer. X indicates the sensor was not used for a given set-up. Values from sensors shown in parentheses (those on the right wing for non acceleration-compensated experiments) were measured but are not discussed here.
