Are there any programs or codes widely used for computing spherical multipole expansion, especially for CMB?
I have data of coordinates and values of a part of sky, and I'm supposed to calculate multipole expansion, change some components between some $\ell$s, and finally calculate back to values. The ...
I am looking for an implementation of the Maximum Entropy Method for image deconvolution, ideally in MATLAB or Mathematica. I'm trying to reconstruct an image from fringe visibilities, as is often ...
I have always been interested in space and astronomy (in my youth - I wanted to be an astronaut). However for various reasons, I never quite got started. I now want to get started - small but ...
Which sky map application for mobile devices have the best "feature satisfaction"-to-investment ratio? I would like to have a comparison between "sky map" applications for mobile devices and it ...
I need to produce custom star charts for my website. I want to be able to do the following: Specify a region, maybe a constellation or just an arbitrary region Specify what appears on the chart ...
I used until now only stellarium.org and I'm curious if there is any other software that is better than stellarium. By better, I mean: doesn't have high system ...
Given an astrophoto with a resolution between 0.5 and 5 arcseconds per pixel, which ways exist to identify the direction of view, field of view, and objects in the picture? I believe most amateur ...
Are there websites or programmes that permit a simulation of the night sky in the past and the future on an ordinary computer?
Are there websites or programs that permit a simulation of the night sky in the past and the future on an ordinary computer? (For the past, I would be content with objects visible to the naked eye.) ...
I need to process some images taken from a telescope to determine the intensity of an astroid. This way I can determine the rotation period of this asteroid. The pictures were taken the usual way ...
