Software & Code

This page collects open-source modeling software and small astronomy utilities developed during my research work. Older GILDAS and IDL scripts are provided as lightweight, task-specific tools.

RADEX + emcee (Python code)

Perform non-LTE modeling with MCMC (emcee+RADEX). This code combines emcee and RADEX, performing MCMC sampling on the RADEX-parameters space without predefined grids, which leads to faster convergence time and a better sampling of the parameter space.

Extract spectra from uvfit/image files (GILDAS script)

These scripts extract the velocity, flux, and flux error in each channel from the current *.UVFIT file after uvfit, or from a selected region in GILDAS go view. The resulting spectrum is stored in an ASCII file.

Download uvfit2txt.map and spec2txt.map.

Plotting radial integrated profile from FITS images (IDL)

This script calculates the integrated power within a chosen radius of a FITS image and its growth with radius. It is useful for quick checks of whether a source is extended or contains ring- or disk-like structure.

Filling histogram-style (psym=10) spectral plot with colors (IDL)

This IDL routine fills the area between a histogram-style (PSYM=10) spectrum and its continuum, which is not handled directly by POLYFILL. It can be used for spectra such as CO, HCN, and CS.
