The HST/WFC3 IR Point Spread Function: A 13-Year Empirical Characterization for Precision Astronomy in the JWST Era Tony Eugene Ford Independent Researcher Abstract We present the first systematic empirical characterization of the Hubble Space Telescope’s Wide Field Camera 3 infrared channel (WFC3/IR) point spread function, analyzing 512 high-quality PSF measurements from 13 years of archival observations (2010–2023). Using a statistically robust sample across multiple filters with precise focus values (–2.0 to +2.0 µm), we quantify: (1) focus-dependent FWHM variations of 18.7% across the operational range, following a parabolic relationship with minimum at focus =–0.2 µm (FWHM(focus) = 1.92 + 0.031·focus2 pixels, R2 = 0.89); (2) exceptional photometric stability with RMS variations <2.3% over decade timescales; (3) astrometric precision of 20.3 ± 8.7 milliarcseconds, enabling detection of 0.5MJup exoplanets at 10 pc; and (4) empirical detection limits for anomalous PSF

DeaDBeeF is a modular cross-platform audio player, which runs on GNU/Linux distributions, macOS, Windows, *BSD, OpenSolaris, other UNIX-like systems. DeaDBeeF plays a variety of audio formats, converts between them, lets you customize the UI in almost any way you want, and use many additional plugins which can extend it even more.

ExCon can create images with a very wide field of view (more than billion pixels). It implements novel gridding and image weighting algorithms. It is well suited to make ultra deep radio interferometric images, minimizing aliasing artefacts and PSF variation. NVIDIA GPU acceleration is available. JAVA/SCALA support available.

This package of MATLAB routines with accompanying GUI allows scientific users to measure the 3D location of single molecules when using the double-helix point spread function (DH-PSF) widefield microscope. Version 2 also includes code that facilitates combining localization data from two spectral channels using a locally-weighted quadratic 3D registration function Features - Double-Gaussian estimator is calibrated via an axial scan of bright immobile fluorescent emitters (e.g. beads) - DH localization is performed through template matching and subsequent double Gaussian fitting - Tiff stacks of SM images are analyzed using template matching followed by double-Gaussian fitting to extract estimates of the molecule positions - Two spectral channels are registered by generating a locally-weighted quadratic mapping function from control point pairs

...It includes tools to extract, optimize, and build VGM formats as well as auditing and exploration utilities. [GBS, KSS, MDX, NSF(E), SID, S98, SPC, VGM, XA, XMA, xSF (PSF/PSF2/etc)]

Simple dialog window to calculate the Standard Atmosphere properties (namely Temperature, Pressure, Density, and Speed of sound) using the altitude as input. It uses the published US Standard Atmosphere 1976 set of equations. Different unit conversions can be done directly within the interface. Useful for preparing CFD boundary conditions. The executable will write an .ini file from within the same folder it is launched. The ini file retrieves the interface options as well as positioning...

This package includes a collection of MATLAB files which are designed to: 1. Given a calibration scan of the image of a point emitter with an engineered point spread function (PSF), 2. Perform a phase retrieval algorithm based on maximum likelihood estimation (MLE) of a phase aberration term which is added to the theoretical pupil function of the imaging system. 3. Use the phase-retrieved pupil function to perform single-emitter localization. Accompanying publication available here: https://doi.org/10.1364/OE.25.007945

This software attempts to recover licence plates characters (or other kind of characters) from videos using information redundancy of several frames. The user sets boundaries and the software overlaps images. An average image is created whose definition is limited by user imprecision and PSF of the lens. The software does not try to make debluring, instead, all possible combinations of characteres are generated and correlations are calculated using the images.

PSF is a path-sensitive, inter-procedural program analysis framework developed on top of Soot.

The aim of the PL-PSF project is to create a generic domain-independent combinatorial problem solver. It uses a petri-nets based model to represent the problems and problem decomposition/abstraction with graph topology analysis to solve them.
