Forced photometry
WebAug 24, 2010 · Forced perspective is a technique that employs optical illusion to make an object appear farther away, closer, larger or smaller than it actually is. It is used primarily … WebThe forced photometry approach has the advantage that we measure a consistent set of sources between SDSS and WISE, taking advantage of the resolution and depth of the SDSS images to interpret the WISE images; objects that are resolved in SDSS but blended together in WISE still have accurate measurements in our photometry.

Web• This process is sometimes called forced photometry – “forced” because a detection of a source (say >5σ) in one survey is used to measure fluxes of that source in other surveys, … WebWe announce the public release of the ATLAS forced photometry server, which provides public access to photometric measurements over the full history of ATLAS survey. …
WebMar 19, 2009 · By conducting forced photometry at the SN position and by adding artificial stars to our postexplosion i′ image and attempting to recover them using the ISIS package, we conservatively estimate that the upper brightness limit for a single point source is m i (AB) > 26.3 at the SN location. WebJun 4, 2024 · Forced photometry is a technique that was developed to deal with issues arising from cross-matching between sky surveys conducted at different wavelengths and/or different telescopes. Depending on the shapes of their (observed-frame) spectral energy distributions, different sources may or may not be formally detected in different surveys.
