glespy 0.1.7.2

Bindings for GLESP for calculations with spherical harmonics

This package contains line bindings for GLESP with some ‘candies’:

Installation

Requirements

• GLESP must be installed with all dependences for normal work;

• numpy to work with dl$

• eog (to show maps).

Installation

To install package just input to command line:

pip install glespy

Using

To use in python you need to import glespy package

import glespy

Features

Automated parameters control, i.e.:

lmin >= 0
lmax >= lmin
nx >= lmax * 2 + 1
np >= nx * 2

PixelMap

Class for GLESP fits pixel maps. Possible operations are:

• arithmetics (+, -, *, …);

• convert from alm GLESP files;

• draw map (with eog, if it’s installed);

• get map attributes;

• cut/keep zones;

• reflect map;

• mask map;

• get C(l), alm and gif.

Alm

Class for GLESP fits alm. Operations:

• get attributes;

• convert to GLESP pixel map;

• smooth;

• rotate;

• get C(l).

PointSource

Class for getting GLESP fits map from file with ascii values. It can be with point sources or pixel map in ascii format. Operations:

• get pixel map;

• show.

Cl

Class for manipulating with angular power spectrum. Operations:

• convert to alm;

• convert to pixel map.
