Astronomical observations in the molecule rich 3 mm window using large reflector antennas provide a unique view of the Universe. To efficiently carry out these observations gravitational and thermal deformations have to be corrected. Terrestrial lase

Several recent investigations indicate the existence of gender-related systematic trends in the peer review of proposals for observations on astronomical facilities. This includes the National Radio Astronomy Observatory (NRAO) where there is evidenc

To carry out astronomical observations in the molecule rich 3 mm window the Green Bank Telescope (GBT) compensates for gravitational and weather induced deformations of its primary reflector. Terrestrial laser scanners (TLSs) offer a fast and reliabl

In Hunt et al., we used the Anderson–Darling (AD) two-sample test to evaluate the probability that the observed linear rank distributions for female and male principal investigators are from the same parent sample. We determined the nominal AD p-va

Wind-induced pointing errors are a serious concern for large-aperture high-frequency radio telescopes. In this paper, we describe the implementation of an optical quadrant detector instrument that can detect and provide a correction signal for wind-i

We present a 30 - 50 GHz survey of Sagittarius B2(N) conducted with the Australia Telescope Compact Array (ATCA) with 5 - 10 arcsec resolution. This work releases the survey data and demonstrates the utility of scripts that perform automated spectral

Methods are described to calibrate and model a dual-axis inclinometer, using a single-axis sine bar, by rotating the inclinometer axially on the sine bar and using a cross-coupled polynomial expansion model. A simple combination of angle blocks and f

We describe the successful design, implementation, and operation of a 12 GHz holography system installed on the Robert C. Byrd Green Bank Telescope (GBT). We have used a geostationary satellite beacon to construct high-resolution holographic images o
