deepSIP (deep learning of Supernova Ia Parameters) measures the phase and light-curve shape of a Type Ia Supernova (SN Ia) from an optical spectrum. The package contains a set of three trained Convolutional Neural Networks (CNNs) for the aforementioned purposes, but tools for preprocessing spectra, modifying the neural architecture, training models, and sweeping through hyperparameters are also included.
PIPS analyzes the lightcurves of astronomical objects whose brightness changes periodically. Originally developed to determine the periods of RR Lyrae variable stars, the code offers many features designed for variable star analysis and can obtain period values for almost any type of lightcurve with both speed and accuracy. PIPS determines periods through several different methods, analyzes the morphology of lightcurves via Fourier analysis, estimates the statistical significance of the detected signal, and determines stellar properties based on pre-existing stellar models.
