Detailed Description

template<typename T, typename I, typename M>
class lsst::gauss2d::fit::Data< T, I, M >

A list of Observation instances that can be modelled.

A Data is a list of Observation instances that can have associated Model instances. Multiple Observation instances may have the same Channel, but one should not include the same Observation multiple time.

Template Parameters

T	The type of the Observation Image (usually float or double)
I	The type of the Observation indices (usually size_t)
M	The type of the Observation Mask (usually bool)

Return a full, callable string representation of this.

Parameters

name_keywords	Whether to prefix arguments with "{name}=", where name is the arg name in the header (as with keyword arguments in Python).
namespace_separator	The string to use to delimit namespaces, i.e. :: in C++ and . in Python.

Returns

A callable string representation of this, which should return an an identical object to this.

Note

The representation with name_keywords=false must be callable in C++. The representation with name_keywords=true should be callable in Python, if there are any bindings.
