Abstract
In August and October 1900 FOS spectra of the internal Pt-Cr-Ne
calibration lamps were obtained with the red and blue detectors
respectively, througb a set of paired apertures (the 0.1 and 0.25) and
through the centered 0.3 circular aperture. These spectra give the
initial dispersion solutions for the FOS gratings and prisms, and they
will serve as reference template spectra for future calibrations. The
wavelength solutions show shifts of less than two diodes from
pre-fiight calibrations on the blue side and less than three diodes on
the red side. Root-mean-square residuals are typical of those found
from the ground calibration data.
