Detailed Description

The MOKA map structure, containing all quantities that define it.

The MOKA map, that is read in from the fits file. Its components include the lensing properties, as well as the cosmology, the size of the field of view, the redshifts of the lens and source, the properties of the cluster, etc.

Note: To use this class requires setting the ENABLE_FITS compiler flag and linking the cfits library.

Member Function Documentation

write()

void LensMap::write

(

std::string

filename

)

write the fits file of the maps of all the lensing quantities.

Unlike the read operations this will not have the h factors in everything so when reading from a file created by is you should set h to 1
