- ISEE-1 Energetic Ion Mass Spectrometer Data
- Short Name:
- ISEE Ion Data

- Publisher:
- NASA
- Description:
- Ion data from the Plasma Composition Experiment on ISEE-1 consist of a combination of (a) velocity moments for the four principal magnetospheric ion species H+, He++, He+, and O+, calculated in two different ways (using two different sets of assumptions) and covering the 0.01-0.1 and 0.1-16 keV/e energy ranges, (b) energy-angle spectra for the same four ions plus O++, covering the 0.01-17.9 keV/e range, and (c) mass spectra (<1 amu/e to about 150 amu/e) for four energy ranges, all derived once per each complete energy-mass scan cycle of the instrument, or once each 1- to 20-minute interval, depending on mode of operation, as well as (d) "total ion" moments, derived once per energy scan and assuming total count rate is due to H+ ions (0.1-16 keV).

- ISEE-1 Ion Composition Data Parameter Plots
- Short Name:

- Date:

- Publisher:
- NASA
- Description:
- These hardcopy plots were provided as a supplement to the digital data from the Plasma Composition Experiment (NSSDC data set 77-102A-12I). A subset of the data in the digital data files is plotted in graphical form in a series of booklets, one booklet for each month of data. There are two pages of graphs for each day, and each page has a stack of 7 panels showing the variation of different parameters during the course of a 12-hour Universal Time interval. Panel 1 (top panel) shows densities of He++, He+, and O+ ions, and the "total" ion density (per cubic meter); Panel 2 shows He++/H+ density ratio; Panel 3 shows ion "thermal" energy (eV); Panel 4 shows "thermal" energy density multiplied by 2/3 along with the magnetic pressure (eV/m^3) and field strength (nT); Panel 5 shows ion drift speed (meters/sec) in the GSE X-Y plane; Panel 6 shows magnetic field elevation angle (degrees) relative to the GSE X-Y plane; Panel 7 shows ion drift angle and the magnetic longitude angle.

- Publisher:
- NASA
- Description:
- NSSDC is the permanent archive for NASA space science mission data: astronomy and astrophysics, solar and space plasma physics, and planetary and lunar science. As permanent archive, NSSDC teams with NASA's discipline-specific space science "active archives" which provide access to data to researchers and to the general public. NSSDC also serves as NASA's primary active archive for space physics mission data and for selected NASA astrophysics missions. It provides access to several geophysical models and to data from some non-NASA mission data. In addition to supporting active space physics and astrophysics researchers, NSSDC also supports the general public both via several public-interest web-based services (e.g., the Photo Gallery) and via the offline mailing of CD-ROMs, photoprints, and other items. NSSDC provides online information about NASA and non-NASA spacecraft and experiments, and about data management standards and technologies.

- OAO-2 Ultraviolet Spectra: An Atlas of Stellar Spectra
- Short Name:
- OAO-2
- Date:
- 24 Apr 2006 21:24:06
- Publisher:
- NASA
- Description:
- This data set is a subset of ultraviolet stellar spectra comprising the highest quality data obtained with both spectrometers aboard the OAO 2. The first file of the data set contains ultraviolet stellar fluxes for 164 bright stars in the spectral range between 1200 to 1300 A, with resolutions of about 22 A in the region from 3600 to 1850 A and about 12 A in the region from 1850 to 1160 A. Files 2 and 3 contain spectra for 132 stars in the region 1200-1850 A and 34 stars in the region 1800-3600 A, respectively, with resolutions as stated above. The data have been published in graphical and tabular form by A.D. Code and M.R. Meade, Astrophys. J. Suppl., v. 39, p. 195, 1979; M.R. Meade and A.D. Code, Astrophys. J. Suppl., v. 42, p. 283, 1980.

- Skylab Catalog of Far-Ultraviolet Objective-Prism Spectrophotometry
- Short Name:
- Skylab FUV
- Date:

- Publisher:
- NASA
- Description:
- This data set is a machine-readable version of the catalog of Far- Ultraviolet Objective-Prism Spectrophotometry (S-019). The data are on one ASCII tape with two files, created on an IBM 3081 computer. The data set contains arrays of ultraviolet flux measurements at wavelengths of 1300 to 4200 A. The spectra were digitized with a PDS 1010 A microdensitometer, and each spectrum was scanned in a series of strips 30 microns wide. This catalog contains data on 494 stars. The data on each star are quite complex and include a number of parameters in addition to the adopted fluxes. Accompanying this data set is a copy of a document entitled "Documentation for the Machine-Readable Version of the Catalogue of Far-Ultraviolet Objective-Prism Spectrophotometry: Skylab Experiment S-019, Ultraviolet Stellar Astronomy" by R.S. Hill and L.E. Brotzman, 1984 (B35702-000A). For more information on this data set, see the above document or contact Dr. Karl Henize, Code SN3, NASA Johnson Space Center, Houst

- Description:
- Viking 1 Gas Exchange, Labeled Release, and Pyrolytic Release Data on Microfilm. These data, supplied by the investigation team, are on 16- mm microfilm and consist of descriptions of the commands that were sent to operate the three instruments, and tabulations of raw and reduced data returned. The command data include Mars time for each experiment sequence, the commands sent, predicted data points for each command file that were used to time tag the data when it came back from the instrument, and a summary of the major events of each command sequence.
