Data Fields | |
int | verbosity |
int | reality |
int | upsample |
double | B |
int | L |
int | J_min |
int | N |
int | spin |
int | original_spin |
s2let_sampling_t | sampling_scheme |
ssht_dl_method_t | dl_method |
A struct with all parameters that are common to several functions of the API. In general only one struct needs to be created and a const pointer to it is passed around.
double s2let_parameters_t::B |
Wavelet parameter which determines the scale factor between consecutive wavelet scales.
ssht_dl_method_t s2let_parameters_t::dl_method |
Recursion method to use for computing Wigner functions.
int s2let_parameters_t::J_min |
First wavelet scale to be used.
int s2let_parameters_t::L |
Upper harmonic band-limit. Only flmn with l < L will be stored and considered.
int s2let_parameters_t::N |
Upper azimuthal band-limit. Only flmn with n < N will be stored.
int s2let_parameters_t::original_spin |
If normalization has value S2LET_WAV_NORM_SPIN_LOWERED this parameter indicates which spin number the wavelets were lowered from. Otherwise, it is ignored.
int s2let_parameters_t::reality |
A non-zero value indicates that the signal f is real. Not all functions respect this value - instead there may be separate complex and real functions. See the documentation of each function for details.
s2let_sampling_t s2let_parameters_t::sampling_scheme |
Sampling scheme to use for samples of the signal f as well as the wavelets.
int s2let_parameters_t::spin |
Spin number of the signal f.
int s2let_parameters_t::upsample |
A non-zero value indicates that the signal is stored in a full-resolution format, where each wavelet scale is upsampled to use the same amount of pixels. A zero-value indicates that the signal uses only as many pixels as necessary for each wavelet scale's upper harmonic bandlimit. This can lead to significant storage and time savings and is the default behaviour.
int s2let_parameters_t::verbosity |
Detail level for diagnostic console output in range [0,5].
