2) Is there a transmission curve that is more finely sampled? The current one has only 32 bins over the 271-1087 nm wavelength range.
And there is also this statement: “Extrapolations at short and long wavelengths to cover 300-1100nm”, which is concerning because now I am not sure how much of the transmission curve was actually measured and how much was extrapolated.
That’s an excellent question! As you know I have a survey program using the B600 as well, and so I would also be very interested to know the answer to this.
By convolving the grating transmission, detector response and stellar blackbody I get something that is different from what I observe in the data, so perhaps the grating transmission information does need to be updated.
