[ascl:2507.023] Capivara: Scalable spectral-based segmentation package
Capivara implements a spectral-based segmentation method for Integral Field Unit (IFU) data cubes. The code uses hierarchical clustering in the spectral domain, grouping similar spectra to improve the signal-to-noise ratio without compromising astrophysical similarity among regions, and leverages advanced matrix operations via torch for GPU acceleration.
[ascl:1107.010] XDSPRES: CL-based package for Reducing OSIRIS Cross-dispersed Spectra
The CL-based package XDSPRES is a complete reducing facility for cross-dispersed spectra taken with the Ohio State Infrared Imager/Spectrometer, as installed at the SOAR telescope. This instrument provides spectra in the range between 1.2um and 2.35um in a single exposure, with resolving power of R ~ 1200. XDSPRES consists of two tasks, namely xdflat and doosiris. The former is a completely automated code for preparing normalized flat field images from raw flat field exposures. Doosiris provides a complete reduction pipeline that requires a minimum of user interaction. The user guide explains the general steps towards a fully reduced spectrum.
[ascl:1105.002] PACCE: Perl Algorithm to Compute Continuum and Equivalent Widths
PACCE (Perl Algorithm to Compute continuum and Equivalent Widths) computes continuum and equivalent widths. PACCE is able to determine mean continuum and continuum at line center values, which are helpful in stellar population studies, and is also able to compute the uncertainties in the equivalent widths using photon statistics.
