Supporting data package for TR 32-1541, effects of storage temperatures on silicon solar cell contacts
A series of summary curves is presented for cells having various contact systems, depicting the effects of temperature exposure as a function of time on the electrical and mechanical characteristics. Each curve represents the results obtained from a minimum of 32 and a maximum of 1104 individual data inputs and includes the 95% confidence limits associated with each time-temperature combination for which measurements were obtained. The curves are useful for detailed analysis and comparison of the behavior of the contact system as a function of the environmental conditions studied.

FORMAC integration program: A special applications package used in developing techniques of orbital decay and long term ephemeris prediction for satellites in earth orbit
The symbolic manipulation capabilities of the FORMAC (Formula Manipulation Compiler) language are employed to expand and analytically evaluate integrals. The program integration is effected by expanding the integral(s) into a series of subintegrals and then substituting a pre-derived and pre-coded solution for that particular subintegral. Derivation of the integral solutions necessary for precoding is included, as is a discussion of the FORMAC system limitations encountered in the programming effort.

Skylab 4 preliminary reference Earth Resources Experiment Package (EREP) pass planning document. Volume 1: Groundtracks
Ground tracks and some ground track-associated parameters of the Skylab 4 (SL-4) mission are presented for a rapid evaluation and determination of EREP passes. The data are based on an SL-1 launch at 17h 30m 0.00s Greenwich mean time on 30 April 1973.

Skylab 4 preliminary reference Earth Resources Experiment Package (EREP) pass planning document. Volume 2: EREP sites and S190 swath study of selected revs
Ground tracks with s190 swaths of selected revolutions as they pass over areas containing EREP sites are presented. Most of the data consists of passes over the continental United States; several are shown over Australia and South America. The S190 is a 6-channel high precision 70 mm camera facility.

An improved multiple linear regression and data analysis computer program package
NEWRAP, an improved version of a previous multiple linear regression program called RAPIER, CREDUC, and CRSPLT, allows for a complete regression analysis including cross plots of the independent and dependent variables, correlation coefficients, regression coefficients, analysis of variance tables, t-statistics and their probability levels, rejection of independent variables, plots of residuals against the independent and dependent variables, and a canonical reduction of quadratic response functions useful in optimum seeking experimentation. A major improvement over RAPIER is that all regression calculations are done in double precision arithmetic.

Balloon-borne package temperature controller
Simple, inexpensive, lightweight enclosure traps upward long wave radiation of earth while reflecting harsh solar radiation in upper atmosphere. It warms enclosed instruments in cold regions and protects them from overheating during the day. Device can be attached to balloon system without any changes in experimental design.

Thermal Control of the Scientific Instrument Package in the Large Space Telescope
The general thermal control system philosophy was to utilize passive control where feasible and to utilize active methods only where required for more accurate thermal control of the SIP components with narrow temperature tolerances. A thermal model of the SIP and a concept for cooling the SIP cameras are presented. The model and cooling concept have established a rationale for determining a Phase A baseline for SIP thermal control.

The earth resources experiment package on Skylab and proposed resource investigations.
In late 1973, NASA plans to launch a three-man experimental space station, the Skylab Workshop. Technical specifications regarding the instrumental facilities of the space station are presented, giving attention to the multispectral photographic facility, the IR spectrometer, the multispectral scanner, the L-band radiometer, and the S-193 sensor. The S-193 sensor will provide data applicable to studying varying ocean surfaces, wave conditions, sea and lake ice, ocean clouds, weather prediction, and soil types. All data from the sensors will be recorded on film and analog magnetic tape for return at the end of each manned period of Skylab.
