Definition at line 56 of file healpix_map.h.

◆ Healpix_Map() [4/4]

template<typename T>
Healpix_Map< T >::Healpix_Map ( const arr< T > &  data,
Healpix_Ordering_Scheme  scheme 
)
inline

Constructs a map from the contents of data and sets the ordering scheme to Scheme. The size of data must be a valid HEALPix map size.

Definition at line 61 of file healpix_map.h.

Member Function Documentation

◆ Set() [1/2]

template<typename T>
void Healpix_Map< T >::Set ( arr< T > &  data,
Healpix_Ordering_Scheme  scheme 
)
inline

Deletes the old map, creates a map from the contents of data and sets the ordering scheme to scheme. The size of data must be a valid HEALPix map size.

Note
On exit, data is zero-sized!

Definition at line 68 of file healpix_map.h.

◆ Set() [2/2]

template<typename T>
void Healpix_Map< T >::Set ( int  order,
Healpix_Ordering_Scheme  scheme 
)
inline

Deletes the old map and creates a new map with a given order and the ordering scheme scheme.

Definition at line 76 of file healpix_map.h.

◆ SetNside()

template<typename T>
void Healpix_Map< T >::SetNside ( int  nside,
Healpix_Ordering_Scheme  scheme 
)
inline

Deletes the old map and creates a new map with a given nside and the ordering scheme scheme.

Definition at line 83 of file healpix_map.h.

◆ fill()

template<typename T>
void Healpix_Map< T >::fill ( const T &  val)
inline

Fills the map with val.

Definition at line 90 of file healpix_map.h.

◆ Import_nograde()

template<typename T>
void Healpix_Map< T >::Import_nograde ( const Healpix_Map< T > &  orig)
inline

Imports the map orig into the current map, adjusting the ordering scheme. orig must have the same resolution as the current map.

Definition at line 96 of file healpix_map.h.

◆ Import_upgrade()

template<typename T>
void Healpix_Map< T >::Import_upgrade ( const Healpix_Map< T > &  orig)
inline

Imports the map orig into the current map, adjusting the ordering scheme and the map resolution. orig must have lower resolution than the current map, and this->Nside() must be an integer multiple of orig.Nside().

Definition at line 119 of file healpix_map.h.

◆ Import_degrade()

template<typename T>
template void Healpix_Map< T >::Import_degrade ( const Healpix_Map< T > &  orig,
bool  pessimistic = false 
)

Imports the map orig into the current map, adjusting the ordering scheme and the map resolution. orig must have higher resolution than the current map, and orig.Nside() must be an integer multiple of this->Nside(). pessimistic determines whether or not pixels are set to Healpix_undef when not all of the corresponding high-resolution pixels are defined.

This method is instantiated for float and double only.

Definition at line 37 of file healpix_map.cc.

◆ Import()

template<typename T>
void Healpix_Map< T >::Import ( const Healpix_Map< T > &  orig,
bool  pessimistic = false 
)
inline

Imports the map orig into the current map, adjusting the ordering scheme and the map resolution if necessary. When downgrading, pessimistic determines whether or not pixels are set to Healpix_undef when not all of the corresponding high-resolution pixels are defined.

This method is instantiated for float and double only.

Definition at line 162 of file healpix_map.h.

◆ operator[]() [1/2]

template<typename T>
const T& Healpix_Map< T >::operator[] ( int  pix) const
inline

Returns a constant reference to the pixel with the number pix.

Definition at line 173 of file healpix_map.h.

◆ operator[]() [2/2]

template<typename T>
T& Healpix_Map< T >::operator[] ( int  pix)
inline

Returns a reference to the pixel with the number pix.

Definition at line 175 of file healpix_map.h.

◆ swap_scheme()

template<typename T>
void Healpix_Map< T >::swap_scheme ( )
inline

Swaps the map ordering from RING to NEST and vice versa. This is done in-place (i.e. with negligible space overhead).

Definition at line 179 of file healpix_map.h.

◆ interpolation()

template<typename T>
T Healpix_Map< T >::interpolation ( const fix_arr< int, 4 > &  pix,
const fix_arr< double, 4 > &  wgt 
) const
inline

performs the actual interpolation using pix and wgt.

Definition at line 205 of file healpix_map.h.

◆ interpolated_value()

template<typename T>
T Healpix_Map< T >::interpolated_value ( const pointing &  ptg) const
inline

Returns the interpolated map value at ptg

Definition at line 219 of file healpix_map.h.

◆ Map()

template<typename T>
const arr<T>& Healpix_Map< T >::Map ( ) const
inline

Returns a constant reference to the map data.

Definition at line 228 of file healpix_map.h.

◆ minmax()

template<typename T>
template void Healpix_Map< T >::minmax ( T &  Min,
T &  Max 
) const

Returns the minimum and maximum value of the map in Min and Max.

This method is instantiated for float and double only.

Definition at line 75 of file healpix_map.cc.

◆ swap()

template<typename T>
void Healpix_Map< T >::swap ( Healpix_Map< T > &  other)
inline

Swaps the contents of two Healpix_Map objects.

Definition at line 237 of file healpix_map.h.

◆ average()

template<typename T>
double Healpix_Map< T >::average ( ) const
inline

Returns the average of all defined map pixels.

Definition at line 244 of file healpix_map.h.

◆ Add()

template<typename T>
void Healpix_Map< T >::Add ( val)
inline

Adds val to all defined map pixels.

Definition at line 255 of file healpix_map.h.

◆ Scale()

template<typename T>
void Healpix_Map< T >::Scale ( val)
inline

Multiplies all defined map pixels by val.

Definition at line 263 of file healpix_map.h.

◆ rms()

template<typename T>
double Healpix_Map< T >::rms ( ) const
inline

Returns the root mean square of the map, not counting undefined pixels.

Definition at line 272 of file healpix_map.h.

◆ absmax()

template<typename T>
T Healpix_Map< T >::absmax ( ) const
inline

Returns the maximum absolute value in the map, ignoring undefined pixels.

Definition at line 285 of file healpix_map.h.

◆ fullyDefined()

template<typename T>
bool Healpix_Map< T >::fullyDefined ( ) const
inline

Returns true, if no pixel has the value Healpix_undef, else false.

Definition at line 297 of file healpix_map.h.

◆ replaceUndefWith0()

template<typename T>
tsize Healpix_Map< T >::replaceUndefWith0 ( )
inline

Sets all pixels with the value Healpix_undef to 0, and returns the number of modified pixels.

Definition at line 306 of file healpix_map.h.
