Output Request:
If you want the lensed Cls you will need both.

Sky Map Output:
The HEALpix synfast program is used to generate maps from the resultant spectra.

NSide
Beam Size (arcmin)
Synfast Random # Seed
The random number seed governs the phase of the a_lm's generated by synfast. The default of zero causes synfast to generate a new see from the system time with each run. Specifying a fixed nonzero value will return fixed phases with successive runs.

L max

K eta max

The Bessel function files only support up to (3000,6000).

tf kmax

Num K/log. int.

# Transfer Functions

Redshifts

Separate the redshifts with commas (e.g., 0,1,2).
At least one per transfer function should be provided if any are requested (see the above output request).
If more than one transfer function is requested
then the redshifts must specified in decreasing order.
CMBFAST will not support more than nine (9) transfer functions!
