Figure 3.
Difference in radial
velocity between one of
the three science fibers
and the calibration fiber
for approximately 4,000
etalon lines from 16
orders of the blue arm.
The timespan is 24 hours.
Data were taken with 10
second to 5 minute
cadence. No drift
between the two
fibers is apparent at
the cm/s level with
an RMS of 19 cm/s
for the individual
exposures.
Figure 4.
Small subsection
of a solar spectrum
recorded with
MAROON-X at the
University of Chicago. For
comparison we overplot
the same region from the
solar atlas of Wallace et
al. (2011) obtained with
the Fourier Transform
Spectrometer (FTS)
at the McMath-Pierce
Telescope, reduced to
the spectral resolving
power of MAROON-X
(R = 80,000). In the
bottom of the figure we
show the simultaneously
recorded spectrum from
the MAROON-X etalon
calibrator. The spectra
have been flat-fielded
and are blaze corrected.
At present, the instrument team, with input
from Gemini staff, is designing a front end
for MAROON-X to connect to an instrument
port, while the instrument itself will reside in
the pier lab. We anticipate beginning com-
missioning at the end of 2018 or beginning
of 2019 in order to offer this exciting new set
of capabilities to the Gemini user community.
The MAROON-X team acknowledges fund-
ing for this project from the David & Lucile
Packard Foundation, the Heising-Simons
Foundation, and the University of Chicago.
