Detailed Description

template<typename T>
class Healpix_Map< T >

A HEALPix map of a given datatype

Definition at line 39 of file healpix_map.h.


Constructor & Destructor Documentation

template<typename T>
Healpix_Map< T >::Healpix_Map  )  [inline]
 

Constructs an unallocated map.

Definition at line 46 of file healpix_map.h.

template<typename T>
Healpix_Map< T >::Healpix_Map int  order,
Healpix_Ordering_Scheme  scheme
[inline]
 

Constructs a map with a given order and the ordering scheme scheme.

Definition at line 49 of file healpix_map.h.

template<typename T>
Healpix_Map< T >::Healpix_Map int  nside,
Healpix_Ordering_Scheme  scheme,
const   nside_dummy
[inline]
 

Constructs a map with a given nside and the ordering scheme scheme.

Definition at line 53 of file healpix_map.h.

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 58 of file healpix_map.h.


Member Function Documentation

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.

Definition at line 64 of file healpix_map.h.

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.

Reimplemented from Healpix_Base.

Definition at line 72 of file healpix_map.h.

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.

Reimplemented from Healpix_Base.

Definition at line 79 of file healpix_map.h.

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

Fills the map with val.

Definition at line 86 of file healpix_map.h.

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 92 of file healpix_map.h.

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 higher resolution than the current map.

Definition at line 114 of file healpix_map.h.

template<typename T>
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. 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.

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 160 of file healpix_map.h.

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 171 of file healpix_map.h.

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

Returns a reference to the pixel with the number pix.

Definition at line 173 of file healpix_map.h.

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 177 of file healpix_map.h.

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 227 of file healpix_map.h.

template<typename T>
T Healpix_Map< T >::interpolated_value const pointing ptg  )  const [inline]
 

Returns the interpolated map value at ptg

Definition at line 234 of file healpix_map.h.

template<typename T>
T Healpix_Map< T >::interpolated_value2 const pointing ptg  )  const [inline]
 

Returns the interpolated map value at ptg

Definition at line 242 of file healpix_map.h.

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

Returns a constant reference to the map data.

Definition at line 251 of file healpix_map.h.

template<typename T>
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 79 of file healpix_map.cc.

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

Swaps the contents of two Healpix_Map objects.

Definition at line 260 of file healpix_map.h.

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

Returns the average of all defined map pixels.

Definition at line 267 of file healpix_map.h.

template<typename T>
void Healpix_Map< T >::add val  )  [inline]
 

Adds val to all defined map pixels.

Definition at line 278 of file healpix_map.h.
