This is now fixed in v0.9.0 r260. Previously was mapping an array of
abundances divided by timesteps to each individual entry in the
abundance error scaling array. If the number of abundances exceeded the
number of timesteps this could lead to division by zero errors and, in
any case, would lead to incorrect scalings for most of the abundances.
