Flexure effects within GMOS can result in wavelength zeropoint shifts if the on-sky science data are wavelength-calibrated using daytime CuAr arc exposures.
Access the official MAROON-X Integration Time Calculator (ITC) on a page outside of the Gemini website. The ITC is providing SNR values that can be used to estimate RV expected RV precision using the empirical results provided below.
The latest version of DRAGONS (v3.2.0) was released on 1 April, 2024 and includes fully integrated support for GHOST and support of the new GMOS-S CCDs installed late 2023. With this release, DRAGONS offers support for the science quality reduction of data from the GMOS, NIRI, GSAOI, and F2 imagers, as well as from the GMOS long-slit spectrograph (including nod-and-shuffle observations) and new GHOST high-resolution spectrograph.

In most modes TEXES is background photon noise limited. Since the background brightness and the array efficiency vary considerably with wavelength it can be difficult to calculate the instrument sensitivity at specific wavelengths, but some general rules can be given. For more precise predictions proposers may be able to use the ITC timecalc.xlsx or are encouraged to contact TEXES team members (lacy@astro.as.utexas.edu and tgreathouse@swri.edu). (To use the ITC fill in the white rows of the Object Parameters section.
We strongly advise Mac users running on Apple silicon systems to refrain from updating their operating system to Sonoma 14.4 until further notice.
Updating to this version may result in disruptions to the functionality of our Observing Tool (OT), Phase I Tool (PIT), and other Java based tools.
As part of the Gemini Instrument Upgrade Program GNIRS has gained two new optical sub-systems, namely the LR-IFU and the HR-IFU. The commissioning of both IFUs has now been completed.
Gemini North and South are accepting proposals for the Fast Turnaround (FT) program in this call. Here, we give information specific to this proposal cycle.
The 2024B Gemini Observatory Call for Proposals has been released. Proposals are being accepted for observations from 1 August, 2024 to 31 January, 2025. Gemini North and Gemini South are expected to have 153 and 157 nights available for science, respectively. A new version of the Phase I Tool (PIT) has been released to support proposal submissions.
