This data set is the complete printout submitted by the principal investigator (PI) on the composition of the Venus atmosphere. It consists of a series of scans of the mass spectrum by stepping the ion-accelerating high voltage between successive mass peak tops under the control of a microprocesser. Columns 1 through 3 give the scan number (1-51), telemetry frame number (15-131), and probe altitude above Venus' surface on each page. The remaining 8 columns are the number of ion counts per integration period (235ms) obtained for each mass peak position (at the head of the column) as a function of scan number (equivalent to altitude). Included in the data set is a paper by Hoffman, J. H., et al., IEEE Trans. on Geosci. and Remote Sens., v. GE-18, n. 1, pp. 80-84, 1980.
Digital images (scans) of the entire contents of the microfilm are available as data collection PSPA-00649.
