end program cswt_mask_copy

Generate a coefficient exclusion mask defined in the ecp wavelet coefficient domain by simply converting a list of Healpix sky mask to the wavelet domain.

Notes:

The wavelet coefficients are not actually required in the algorithm, however the wavelet transform structure of the correct size must be initialised. To overcome this problem the tr_mask structure containing the wavelet coefficient masks is often used.

Usage: cswt_mask_copy

[-help]: Display usage information.
[-wcoeff filename_wcoeff]: Name of input wavelet coefficient file initialised with wavelet coefficient tr structure of correct size (convenient to just use saved wavelet transform coefficient file here, see note above).
[-ndil n_dilation]: Number of dilations. (Must be the same as the number of sky files read and the same size as defined in the spherical wavelet coefficient tr stucture.
[-sky filename_sky(i) (repeat n_dil times)]: Sky mask filenames. Parameters are read sequentially on order appear in command line.
[-ext file_extension]: File extension number sky masks are stored in.
[-out filename_out]: Name of output extended coefficient exclusion mask file.
