Crowded - field photometry from HST - imaging ⋆
We present a thorough investigation of stellar photometry based on HST imaging of crowded fields at 85 and 10 from the centre of the high-surface brightness elliptical galaxy M32. The Principal Investigators of the present archive data have elsewhere presented an impressive colour-magnitude diagram of the field at 85. Based on the same data we enlarge on their photometric analysis and supplemen...
متن کاملSpitzer Irac Photometry for Time Series in Crowded Fields
We develop a new photometry algorithm that is optimized for Spitzer time series in crowded fields and that is particularly adapted to faint and/or heavily blended targets. We apply this to the 170 targets from the 2015 Spitzer microlensing campaign and present the results of three variants of this algorithm NASA Exoplanet Science Institute, MS 100-22, California Institute of Technology, Pasaden...
متن کاملThe TAOS Project: High-Speed Crowded Field Aperture Photometry
We have devised an aperture photometry pipeline for data reduction of image data from the Taiwanese-American Occultation Survey (TAOS). The photometry pipeline has high computational performance, and is capable of real-time photometric reduction of images containing up to 1000 stars, within the sampling rate of 5 Hz. The pipeline is optimized for both speed and signal-to-noise performance, and ...

Detecting stars in crowded stellar fields
A comparison is made between some conventional and new methods for detecting stars in crowded stellar images. The new methods are (1) Lucy-Richardson deconvolution of the image before detection, and (2) fitting the Point Spread Function to each pixel in the image. These methods are applied to both a synthetic image and a real one. The deconvolution method looks very promising, and gives better ...
