Figure 17. 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). Figure 18. Telescope time use for semesters 5A to 18A (partial semester, up to July 3rd). The distribution of time used for science and engineering, and lost to faults and weather, is shown. 66 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. GeminiFocus 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- January 2019 / 2018 Year in Review
