McDonald Observatory Column Density Observations of 19P/Borrelly (PDS4 Format)
|
TYPE |
Data
|
DESCRIPTION |
This data set includes the raw column densities of several gas
species observed in the spectra of comet Borrelly, as a function
of position in the coma. All measurements were made with the
2.7-m Harlan J Smith Telescope at McDonald Observatory. During
the 1981 and 1987-1988 apparitions, the data were obtained with
the Intensified Dissector Scanner (IDS), and during the 1994
apparition, the data were obtained with the Large Cassegrain
Spectrograph (LCS).
These data were migrated from the PDS3 dataset
EAR-C-IDS/LCS-3-RDR-BORRELLY-MCDNLD-V1.0.
