Errata corrections are issued for NASA CR-61260 titled “An Empirical Analysis of the 10-15 km Maximum Winds to Determine Apollo and AAP Launch Opportunities.” The document lists amendments to author names on the cover and title page, updates the Government Order number, and corrects table numbering by noting that specific tables (2.9.a and 2.10.a) are reversed. It also corrects pagination for multiple tables and updates the structure of “II: Analysis of Data,” adding a missing “B. Statistics” section describing stochastic maximum wind speeds and their probability interpretation.

SUMMARY

D69-19879 ERRATA The following corrections should be made to NASA CR-61260,"AnEmpirical Analysis of the 10-15 km Maximum Winds to Determine Apolloand AAP Launch Opportunities,Cape Kennedy,Florida,"by Harold L.Crutcher and Nathaniel B.Guttman: (1)On the cover sheet and the title page the authors shouldbe Harold L.Crutcher and Jimmy A.Almazan. (2) On the title page the Government Order should be H-76789. (3)Tables 2.9.a and 2.10.a are reversed. (4)On page 21 the page numbers for Tables 12.12.a,12.12.b, 12.13.a,and 12.13.b should be 278,279,280,and 281,respectively. (5)On pages 283-293,the page numbers for the tables should be numbered consecutively from 295-554. (6) The section on "Statistics was omitted and should be addedon page 3 as Section B of "II:Analysis of Data."It shouldread as follows: # B. Statistics Maximum wind speeds observed in the 10-15 km layer are observedquantities of a random or stochastic variable. The following dis cussionin this paragraph is based on Hald [2]. It is convenient here tointerpret a set of observations of the maximum wind speeds in the 10-15km layer as a random sample drawn from a population of al1 conceivableobservations that may have been made under the same conditions.Theprobability of an event then may be spoken of as the frequency of theevent in the population.When the theory of probability is appliedhere,it is assumed that eventual1y an event wil1 occur with a relativefrequency which is practically equal to its probability. To the extentthen that the data sample of eight years of serially complete record ofthe maximum wind speeds of the 10-15 km layer over Cape Kennedy Florida,is representative of the population,relative frequencies are computedand used as probabilities. Page 2 -ERRATA -NASA CR-61260. Correction(6)continued: Previous work(Crutcher and Quinlan [2])with the maximum wind inthe 10-15 km layer at Cape Kennedy,Florida indicates that a normaldistribution may be used to approximate the upper wind maxima distribu-tion. However,there does exist some correlation in time so the serialdata are not completely independent. Work with the statistical param-eters is reserved for the future. This study presents only the empiricalprobabilities in terms of the wind speeds less than and equal to,orgreater than specified speeds occurring in specified time intervals.The correlation or dependence of data,though of interest,is a part ofthe ensemble and need not be extracted. The data are treated then in thefashing described below. (7) Sections B and C of"II: Analysis of Data!should now benumbered Sections C and D,respectively. # AN EMPIRICAL ANALYSIS OF THE 10-15 KM MAXIMUMWINDS TO DETERMINE APOLLO AND AAP LAUNCHOPPORTUNITIES,CAPE KENNEDY,FLORIDA Harold L.Crutcher,et a l Environmental Science Services AdministrationAsheville,North Carolina January 1969 NASA CONTRACTORREPORT NASA CR-61260 January,1969 NASA CR-61260 AN EMPIRICAL ANALYSIS OF THE 10-15 KM MAXIMUM WINDSTO DETERMINE APOLLO AND AAP LAUNCH OPPORTUNITIES,CAPE KENNEDY,FLORIDA Prepared under NASA Government Order No.H-76789 byHarold L.Crutcher and Nathaniel B.Guttman ENVIRONMENTAL SCIENCE SERVICES ADMINISTRATION For NASA-GEORGE C.MARSHALL SPACE FLIGHT CENTER N 69-19879AceESSiON NUMBER)(THRU)537 日世C126 20 FACILITY FORM 602 # AN EMPIRICAL ANALYSIS OF THE 10-15 KM MAXIMUM WINDSTO DETERMINE APOLLO AND AAP LAUNCH OPPORTUNITIESCAPE KENNEDY,FLORIDA ByHarold L.Crutcher and Nathaniel B.Guttman Prepared under NASA Government Order No.76789 by ENVIRONMENTAL SCIENCE SERVICES ADMINISTRATIONEnvironmental Data ServiceNational Weather Records CenterAsheville,North Carolina Technical Supervisors: S.C.Brown and 0.E.SmithAerospace Environment DivisionAero-Astrodynamics Laboratory Distribution of this report is provided in the interest ofinformation exchange.Responsibility for the contentsresides in the author or organization that prepared it.

FAQs

What changes does the errata require for the authors’ information?

The errata specifies corrected author names on the cover sheet and title page, and also requires that the Government Order be updated to H-76789 on the title page.

Which table ordering and page-number issues are corrected?

The errata states that Tables 2.9.a and 2.10.a are reversed, and it provides corrected page numbers for several tables, including specific fixes for the table locations on page 21 and for the tables spanning pages 283–293.

What section addition and renumbering are included in the errata?

The errata notes that a “Statistics” section was omitted and should be added on page 3 as Section B of “II: Analysis of Data.” It also instructs renumbering of Sections B and C as C and D, respectively, after the insertion.
