Input Flux Distribution

Blackbody T: Kelvin
Power Law Index: F(lambda) is proportional to lambda(Index)
Template Spectra Redshift z: The redshift is only applicable with the option Template Spectra.
Object Magnitude:  Band: Vega AB The object magnitude is only relevant for the three options above.
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
Spatial Distribution: Point Source

Sky Conditions

Days From New Moon: Airmass: Seeing: arcsec
