Resumen:
The Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2)
is a dual-hemisphere, near-infrared (NIR), spectroscopic survey with the
goal of producing a chemodynamical mapping of the Milky Way. The
targeting for APOGEE-2 is complex and has evolved with time. In this
paper, we present the updates and additions to the initial targeting
strategy for APOGEE-2N presented in Zasowski et al. (2017). These
modifications come in two implementation modes: (i) ``Ancillary Science
Programs'' competitively awarded to Sloan Digital Sky Survey IV PIs
through proposal calls in 2015 and 2017 for the pursuit of new
scientific avenues outside the main survey, and (ii) an effective 1.5 yr
expansion of the survey, known as the Bright Time Extension (BTX), made
possible through accrued efficiency gains over the first years of the
APOGEE-2N project. For the 23 distinct ancillary programs, we provide
descriptions of the scientific aims, target selection, and how to
identify these targets within the APOGEE-2 sample. The BTX permitted
changes to the main survey strategy, the inclusion of new programs in
response to scientific discoveries or to exploit major new data sets not
available at the outset of the survey design, and expansions of existing
programs to enhance their scientific success and reach. After describing
the motivations, implementation, and assessment of these programs, we
also leave a summary of lessons learned from nearly a decade of APOGEE-1
and APOGEE-2 survey operations. A companion paper, F. Santana et al.
(submitted; AAS29036), provides a complementary presentation of
targeting modifications relevant to APOGEE-2 operations in the Southern
Hemisphere.
