ML_AFILT2

ML_AFILT2 = [real]
Default: ML_AFILT2 = 0.002

Description: This tag sets the filtering parameter for the angular filtering for ML_IAFILT2 in the machine learning force field method.

This tag is only used if ML_LAFILT2=.TRUE. and ML_IAFILT2=2 are used.

The angular filtering function^[1] for ML_IAFILT2=2 is described as $\eta_{l,a_{\mathrm{FILT}}}=\frac{1}{1+a_{\mathrm{FILT}} [l (l+1)]^{2}}$ . The tag ML_AFILT2 sets the parameter $a_{\mathrm{FILT}}$ .
