Splet24. okt. 2024 · I never really tried the aperture photometry routines within photutils. One of the nice things about PythonPhot's aperture photometry routine is that it allows you to specify a background-measurement annulus so that your star flux is background-subtracted.It also gives you reliable uncertainties on your star magnitudes. SpletThe influent flu gas has a concentration of 5200 mg/m3 of dust particles and a flow rate of 150 m3/s. The smallest particles in the gas stream are 1.5 um in diameter, and all particles have a dielectric constant of 5.5. The emission standard is 50 mg/m3. Assume a plate-to-plate spacing of 30 cm and an applied voltage of 15,000 volts.
