I have a mask/map as a fits file, downloadable here, and I can plot this mask with healpy using this code: It produces this figure: What I want ...

I run healpy.sphtfunc.alm2map passing alm as an array with l_max = 256 and asking as output a map with l_max = 191, but it seems that the function doe ...

I was plotting celestial sphere with equal area binning. My first intention was making a binning based on the basic calculus knowledge which I learned ...

I was trying to work with healpy maps and I am running into a problem with orthographic projections. I want to assign "N" pixels in the healpy mollvie ...

I am running this code using the healpy package. I am not using multiprocessing and I need it to run on a single core. It worked for a certain amount ...

I have three healpy maps (corresponding to three Stokes parameters at different frequencies) and I am trying to plot them together in the same map, to ...

I have a healpix map (nside=256) and I am trying to convolve it with a gaussian, which is not centered, this is, simulating an offset in the 'telescop ...

I have 2-column tables representing the light intensity distribution of a source as a function of its angular radius. These tables were obtained by di ...

I am using HealPix to calculate the outflow rate of particles through a sphere with some radius and I am trying to determine coefficients of spherical ...

I have a full sky convergence map. I would like to cut from this map, smaller square patches in healpy. I would like to know how is this possible. i ...

I am trying to map a FITS data file in python and have started following the healpy documentation available on their website. But I am unable to read ...

I would like to understand a bit better the behavior of rotate_map_pixel() in this particular case. Below I try to provide a minimal toy example: T ...

I am trying to translate a python code into a C code. So I was trying to translate that line: import healpy as hp OldTobySensitivMap = hp.read_map( ...

I have a Healpix Pixel Coordinated file https://wwwmpa.mpa-garching.mpg.de/~ensslin/research/data/faraday2020.html This contains the Latitude and Lon ...

Healpix is a very useful software to do spherical analysis on a sphere. For example, we can use map2alm to analyze a Healpix RING ordered map and retu ...

Can healpy compute the spherical harmonic transform of a complex-valued map? When I try this using healpy.sphtfunc.map2alm, there is no warning, but ...

I have a healpy map that contains an object centered at the location Dec=0 deg and RA=0 deg. Now I want to move the position of the object to an arbit ...

I'm using HEALPy's anafast to extract the Cl's from Planck maps, either the data map [1], or the simulation maps. It seems that even after I apply the ...

Hell everyone, Can Healpy compute a bispectrum of the CMB map? It looks like there is no such built-in function in Healpy library. Thanks! All the ...

I am in need to calculate an integral of spherical harmonics and their products of different orders (l,m) over a fraction of a sphere (let's say for s ...
