Related to C-R model including more than one ion

[pritivish]

hello all,

while running C-R model i found

SetBlocks{den, pref}
which setup the superlevel blocks for the spectral model.
The optional {den} is the abundance of the ion with one less
electron than the lowest charge state included in the model, and {pref} is
the base file name for that ion.

As I understand pref is the base file ion with one less
electron than the lowest charge state included in the model.

but when I an running this, for example I am running the example given in demo/FeL for fe(with 9,11 electrons), atomic data is generated successfully. however when I am running the spec.py neles = range(9,11) is is showing

ERROR: Ionized block 4 of ion 9 does not match a block in file data/Fe08b.en
nlevels = 290 VS -1

I also want to know that does the present CR model includes the ionization balance calculations when I consider more than one ion?
