Constructs an unallocated map.
Definition at line 49 of file healpix_map.h.
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 52 of file healpix_map.h.
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 56 of file healpix_map.h.
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.
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 68 of file healpix_map.h.
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 T_Healpix_Base< int >.
Definition at line 76 of file healpix_map.h.
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 T_Healpix_Base< int >.
Definition at line 83 of file healpix_map.h.
void Healpix_Map< T >::fill | ( | const T & | val | ) | [inline] |
Fills the map with val.
Definition at line 90 of file healpix_map.h.
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.
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.
void Healpix_Map< T >::Import_degrade | ( | 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. 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.
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.
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.
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.
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.
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 204 of file healpix_map.h.
T Healpix_Map< T >::interpolated_value | ( | const pointing & | ptg | ) | const [inline] |
Returns the interpolated map value at ptg
Definition at line 218 of file healpix_map.h.
const arr<T>& Healpix_Map< T >::Map | ( | ) | const [inline] |
Returns a constant reference to the map data.
Definition at line 227 of file healpix_map.h.
void Healpix_Map< T >::minmax | ( | T & | Min, | |
T & | Max | |||
) | const [inline] |
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.
void Healpix_Map< T >::swap | ( | Healpix_Map< T > & | other | ) | [inline] |
Swaps the contents of two Healpix_Map objects.
Definition at line 236 of file healpix_map.h.
double Healpix_Map< T >::average | ( | ) | const [inline] |
Returns the average of all defined map pixels.
Definition at line 243 of file healpix_map.h.
void Healpix_Map< T >::Add | ( | T | val | ) | [inline] |
Adds val to all defined map pixels.
Definition at line 254 of file healpix_map.h.
void Healpix_Map< T >::Scale | ( | T | val | ) | [inline] |
Multiplies all defined map pixels by val.
Definition at line 262 of file healpix_map.h.
double Healpix_Map< T >::rms | ( | ) | const [inline] |
Returns the root mean square of the map, not counting undefined pixels.
Definition at line 271 of file healpix_map.h.
T Healpix_Map< T >::absmax | ( | ) | const [inline] |
Returns the maximum absolute value in the map, ignoring undefined pixels.
Definition at line 284 of file healpix_map.h.
bool Healpix_Map< T >::fullyDefined | ( | ) | const [inline] |
Returns true, if no pixel has the value Healpix_undef, else false.
Definition at line 296 of file healpix_map.h.
tsize Healpix_Map< T >::replaceUndefWith0 | ( | ) | [inline] |
Sets all pixels with the value Healpix_undef to 0, and returns the number of modified pixels.
