Some steps can be sped up significantly if you have access to more than one core. For example, to speed up the single frame processing, you can try adding the -j4 argument. This will attempt to run the processing on 4 cores simultaneously.

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 … WebMay 29, 2024 · Forced photometry is performed at the position of the SN. The nightly zero-point is applied to the photometry to determine the brightness of the SN for that epoch. Small adjustments are made to the SN photometry based on the expectation value from the astrometric uncertainty of the SN centroid.
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. http://www.instantshift.com/2010/08/24/88-brilliant-examples-of-forced-perspective-photography/

Automated triggering, with a human in the loop for monitoring, of follow-up systems has also been implemented.
