Detailed Description

template<typename ReturnT>
class lsst::afw::math::Chebyshev1Function1< ReturnT >

1-dimensional weighted sum of Chebyshev polynomials of the first kind.

f(x) = c0 T0(x') + c1 T1(x') + c2 T2(x') + ... = c0 + c1 T1(x') + c2 T2(x') + ... where:

• Tn(x) is the nth Chebyshev function of the first kind: T0(x) = 1 T1(x) = 2 Tn+1(x) = 2xTn(x) + Tn-1(x)
• x' is x offset and scaled to range [-1, 1] as x ranges over [minX, maxX]

The function argument must be in the range [minX, maxX].

clone()

template<typename ReturnT >

std::shared_ptr<Function1<ReturnT> > lsst::afw::math::Chebyshev1Function1< ReturnT >::clone ( ) const

Return a pointer to a deep copy of this function.

This function exists instead of a copy constructor so one can obtain a copy of an actual function instead of a useless copy of the base class.

Every concrete subclass must override this method.

Returns

a pointer to a deep copy of the function

write()

void lsst::afw::table::io::Persistable::write ( OutputArchiveHandle &  handle ) const

protectedvirtualinherited

Write the object to one or more catalogs.

The handle object passed to this function provides an interface for adding new catalogs and adding nested objects to the same archive (while checking for duplicates). See OutputArchiveHandle for more information.

writeFits() [2/3]

void lsst::afw::table::io::Persistable::writeFits ( fits::MemFileManager &  manager, std::string const &  mode = "w"  ) const

inherited

Write the object to a FITS image in memory.

Parameters

[in]	manager	Name of the file to write to.
