lentil.radiometry.vegaflux

lentil.radiometry.vegaflux(band, waveunit='nm', valueunit='photlam')

Get the flux of Vega in a desired observing band.

Band	Central Wavelength	Flux
U	360 nm	1790 Jy
B	438 nm	4036 Jy
V	545 nm	3636 Jy
R	641 nm	3064 Jy
I	798 nm	2416 Jy
J	1220 nm	1589 Jy
H	1630 nm	1021 Jy
K	2190 nm	640 Jy
W1	3353 nm	310 Jy
W2	4603 nm	172 Jy
W3	11561 nm	31.7 Jy
W4	22088 nm	8.36 Jy

Parameters:

• band (str) – Observing band.

• waveunit (str) – Wavelength units, as accepted by Unit(). Default is nm.

• valueunit (str) – Flux units, as accepted by Unit(). Default is photlam.

Returns:

• flux (float) – Vega flux in band expressed in valueunit

• wave (float) – Central wavelength in band expressed in waveunit
