== Notes ==

# When an optional element ('''''Idev''''', '''''Qdev''''', ...) is used, it must be given in every [[cansas1d_Idata | '''Idata''']] within the enclosing [[cansas1d_SASdata | '''SASdata''']].
# If either '''''dQw''''' or '''''dQl''''' are used, then '''''Qdev''''' is not permitted to be used.
