RAMPS-Data: Radio Ammonia Mid Plane Survey

The Radio Ammonia Mid-Plane Survey (RAMPS) is a large international project that surveys 24 degrees2 of the Galactic Plane using the Green Bank Telescope (GBT). These observations survey the Galactic Plane in the northern hemisphere from l = 10o to l = 40o and b = -0.4o to b=0.4o. This provides the northern hemisphere observations of ammonia and water masers, which are complementary to the observations provided by the H2O southern Galactic Plane Survey (HOPS) using the Mopra single-dish in Australia.

Details about the reduction and processing of this data can be found in Hogge et al. 2018.

Click the image map areas below to view data for that region.

The data files are named with the following conventions:

The region of the sky is listed by the Galactic Longitude center point of the data cube with the data containing a degree of data. This convention means that certain portions of the sky will appear in two data cubes. Both of these cubes are listed for each data block selected on the map below.

The data is listed by molecule and in the case of Ammonia, also sorted by transition. The data files for the derived products can be found in the Derived Data Products. If a folder is empty for a certain molecule/transition that means there is no data for that specific transition at the selected portion of the map. 

The entire directory can be accessed outside of navigating through each region at www.gb.nrao.edu/GbtLegacyArchive/RAMPS

The descriptions of the file names can be found at the readMe document here. This document is also included in the main RAMPS directory.
