2-Hr Averaged Particle Count-Rate Plots (Digitized)


Availability: Data Identified but not Received

Time span: 1972-01-26 to 1972-02-05


This collection consists of digitized microfilm frames containing plots of particle fluxes, as provided by the experimenter. Each time interval is covered by 10 frames, each having two traces, representing all the counting modes of the experiment. Although some characters on the microfilm frames are illegible, the supporting documentation permits ready use of the plots. Each frame covers 10 days and contains 2-h-averaged fluxes. Finer time scale flux plots are given in NSSDCA data sets PSFP-00720 and PSFP-00721.

For this digitization effort the NSSDCA scanned the source microfilm collection PSFP-00083 at a resolution of 400 dots per inch and output each frame on the film as one TIFF file. The NSSDCA also combined groups of these TIFF images into multipage PDF files to facilitate browsing. Both formats are included in this collection.
