The percentage of 13B
to 18A (partial semester,
up to July 3rd) programs
that obtained 80% or
more of their science
time in each semester.
Regular queue and Large
and Long Programs are
included, but not Fast
Turnaround or Director’s
Discretionary programs.
Low completion rates
correspond to poor-
weather semesters (e.g.,
North 16B and 18A; South
15A-16A and 17A) or
dome problems (North
13B and 14A).

of time used for science
and engineering,
and lost to faults and
weather, is shown.

2018A Weather
The weather loss at Gemini North was a
record high (in 18A as of early July). The
weather loss of more than 55% is similar to
what Gemini South suffered in 16A (see the
April 2016 issue of GeminiFocus, page 17).
In both cases the science program comple-
tion suffered greatly (Figures 17 and 18).
Due to the newly implemented “persistent
band 1” philosophy, many of the 18A Band
1 programs in the North will be extended
into 18B and will have future opportunities
to get data.

New Data Reduction
Cookbook for FLAMINGOS-2
A new data reduction cookbook for FLA-
MINGOS-2 is now available. It offers instruc-
tions and PyRAF scripts for the reduction
and calibration of imaging, as well as long-
slit spectroscopy data in an easy-to-follow
format with a focus on the complete pro-
cess. A PDF version is also available by click-
ing on the version tab (see the “v: latest”
icon in the lower right corner of Figure 8).
A Multi-Object Spectrograph (MOS) mode
section will be added with the completion
of the MOS commissioning. Also, remember
that the Getting Started page has informa-
