Performance

Input Flux Distribution

Blackbody T: Kelvin
Power Law Index: F(lambda) is proportional to lambda(Index)
Template Spectra Redshift Z:
Object Magnitude: Band:
Magnitudes are given per square arcsec for extended sources. Note that some template spectra are defined over a limited wavelength range and may not allow calculations for all instrument configurations. The object magnitude is not taken into account for single line sources.
Single line λ: [330-1000] nm FWHM: nm Flux 10-16 ergs/s/cm2 (per arcsec2 for extended sources)
Spatial Distribution:  Point Source Extended Source
