An observational channel, usually representing some range of wavelengths of light.
Definition channel.h:29
virtual bool get_fixed() const =0
Return whether the parameter is fixed (not free).
virtual bool get_linear() const =0
Return whether the parameter is linear.
void insert_param(g2f::ParamBase &param, t &params, ParamFilter *filter=nullptr)
Add a Parameter to a vector thereof, if it meets conditions.
void insert_params(const t params_in, t &params_out, ParamFilter *filter=nullptr)
Same as insert_param, but inserting from a collection of Parameter instances.
void insert_params_ref(const t &params_in, t &params_out, ParamFilter *filter=nullptr)
Same as insert_param, but inserting from a (ref to a) collection of Parameter instances.
lsst::modelfit::parameters::ParameterBase< double > ParamBase
Definition param_defs.h:9
void insert_param_channel(const lsst::gauss2d::fit::Channel &channel, g2f::ParamBase &param, t &params, ParamFilter *filter)
Same as insert_param, but only inserting if filter has a null or matching Channel.
Options for filtering Parameter instances.
