Class HealpixMapFloat
java.lang.Object
healpix.essentials.HealpixTables
healpix.essentials.HealpixBase
healpix.essentials.HealpixMapFloat
- All Implemented Interfaces:
Serializable
Class representing a full HEALPix map containing float values.
This class is conceptually very similar the the Healpix_Map<float>
class of Healpix_cxx.

setNside
Adjusts the object to nside_in.- Overrides:
setNside
in classHealpixBase
- Parameters:
nside_in
- the new Nside parameter- Throws:
Exception
-
setNsideAndScheme
Adjusts the object to nside_in and scheme_in.- Overrides:
setNsideAndScheme
in classHealpixBase
- Parameters:
nside_in
- the new Nside parameterscheme_in
- the new ordering scheme- Throws:
Exception
-
setDataAndScheme
Adjusts the object to scheme_in, and sets pixel data to data_in.- Parameters:
data_in
- pixel data; must have a valid length (12*nside^2)scheme_in
- the new ordering scheme- Throws:
Exception
-
fill
public void fill(float val) Sets all map pixel to a specific value.- Parameters:
val
- pixel value to use
-
swapScheme
Converts the map from NESTED to RING scheme or vice versa. This operation is done in-place, i.e. it does not require additional memory.- Throws:
Exception
-
getPixel
public float getPixel(int ipix) Returns the value of the pixel with a given index.- Parameters:
ipix
- index of the requested pixel- Returns:
- pixel value
-
getPixel
public float getPixel(long ipix) Returns the value of the pixel with a given index.- Parameters:
ipix
- index of the requested pixel- Returns:
- pixel value
-
setPixel
public void setPixel(int ipix, float val) Sets the value of a specific pixel.- Parameters:
ipix
- index of the pixelval
- new value for the pixel
-
setPixel
public void setPixel(long ipix, float val) Sets the value of a specific pixel.- Parameters:
ipix
- index of the pixelval
- new value for the pixel
-
getData
public float[] getData()Returns the array containing all map pixels.- Returns:
- the map array
-
importNograde
Imports the map "orig" to this object, adjusting pixel ordering.- Parameters:
orig
- map to import- Throws:
Exception
-
importUpgrade
Imports the map "orig" to this object, adjusting pixel ordering and increasing resolution.- Parameters:
orig
- map to import- Throws:
Exception
-
importDegrade
Imports the map "orig" to this object, adjusting pixel ordering and reducing resolution.- Parameters:
orig
- map to importpessimistic
- if true, set a pixel to undefined if at least one the original subpixels was undefined; otherwise only set it to undefined if all original subpixels were undefined.- Throws:
Exception
-
importGeneral
Imports the map "orig" to this object, adjusting pixel ordering and resolution if necessary.- Parameters:
orig
- map to importpessimistic
- only used when resolution must be reduced: if true, set a pixel to undefined if at least one the original subpixels was undefined; otherwise only set it to undefined if all original subpixels were undefined.- Throws:
Exception
