spike generates and drizzles point-spread functions (PSFs) for space-based imaging instruments. It supports model and empirical PSF creation for instruments aboard the Hubble Space Telescope (HST), James Webb Space Telescope (JWST), and Nancy Grace Roman Space Telescope (Roman). Spike handles image ingestion, coordinate reading, PSF generation via TinyTim (ascl:1010.057) or WebbPSF/HST empirical methods, and correct drizzling or resampling to match final image processing.

DELIGHT (Deep Learning Identification of Galaxy Hosts of Transients) automatically identifies host galaxies of transient candidates using multi-resolution images and a convolutional neural network. This library has a class with several methods to get the most likely host coordinates starting from given transient coordinates. In order to do this, the DELIGHT object needs a list of object identifiers and coordinates (oid, ra, dec). With this information, it downloads PanSTARRS images centered around the position of the transients (2 arcmin x 2 arcmin), gets their WCS solutions, creates the multi-resolution images, does some extra preprocessing of the data, and finally predicts the position of the hosts using a multi-resolution image and a convolutional neural network. DELIGHT can also estimate the host's semi-major axis if requested, taking advantage of the multi-resolution images.
