Description
rsalm
convolves the map with a symmetric beam via
 |
(19) |
, where
is the expansion in Legendre polynomials of a symmetric beam.
The symmetric beam can be input by reading in an ASCII file
containing the profile of
, or by providing the FWHM for
a symmetric Gaussian beam, where
![\begin{displaymath}
B_{{\ell}}= \exp[- \sigma^2 {\ell}({\ell}+1) / 2 ]
\end{displaymath}](img74.png) |

and
 |

For deconvolution, a simple Tikhonov regularization scheme is always applied via
 |
(22) |
where
is the regularization parameter.
