The new ultra-fast ALMA query-interface

We present the new ultra-fast as-you-type query interface for the ALMA Large Millimeter/submillimeter Array (ALMA). In addition to being search-button-free, the new ALMA query interface features a powerful result table, a view of the observations on the sky through AladinLite as well as a newly developed viewer to visualize the spectral coverage of the observations, all three being linked together.

The interface is fully scalable and shows at startup the entire holdings of ALMA using unlimited virtual vertical scrolling. The sky viewer shows the footprints of the observations, allows to select observations directly for download and includes a slider to fade between sky-background images from gamma-rays to the submillimitre. In addition to the frequency coverage, the spectral coverage viewer shows the atmospheric transmission at the ALMA site as well as molecular line-transitions falling into covered frequency range, fully redshifted to the estimated redshift of the displayed observations.
