... Though the box routines are the preferred way to read blanking information, it is possible to read the blanking information associated with an image directly. Also a routine is needed to write blanking information. ... These routines are: subroutine xyflgrd(tno,index,mask) subroutine xyflgwr(tno,index,mask) subroutine xymkrd(tno,index,runs,n,nread) subroutine xymkwr(tno,index,runs,n) Here tno is the image handle returned by xyopen , index gives the row number (analogous to xyread and xywrite ). ...

... Arithmetic Functions . Random Numbers . String Conversion . Searching and Sorting . ... There are 4 basic integer functions: . int abs(int number); long int labs(long int number); div_t div(int numerator,int denominator); ldiv_t ldiv(long int numerator, long int denominator); . ... In practice no functions produce truly random data -- they produce pseudo-random numbers. ... The stdlib.h provides 2 useful functions to perform general searching and sorting of data on any type. ...

... The Multiple Extension FITS (MEF) file interface is an IRAF library providing facilities for general file operations upon FITS multi-extension files. ... The Multiple Extensions FITS (MEF) interface consists of a number of routines to mainly read a FITS Primary Data Unit or an Extension Unit and manipulate the data at a file level. ... Read the FITS header of a MEF file that matches the EXTNAME or EXTVER keyword values or if not specified, read the extension number `group'. ... The header filename. ...

The English word "array" is translated into Swedish as "f lt" which is retranslated into English as "field". We may therefore perhaps use the word field either by mistake or as a suitable name of a specific array. A new feature of Fortran 90 is that you can work directly with a whole array or an array section without explicit (or implicit) DO -loops. ... An array is defined to have a shape given by its number of dimensions (called " rank ") and the extent for each one of these. ...

... They were determined as a result of orbit improving on the base of all kinds of optical observations available in the catalog of observations of the Minor Planet Center on March 16, 2014 (radar observations have not been used at this stage). ... As the MPC orbits do not all were improved simultaneously with EMP orbits, only 383866 sets of elements were used for data comparison (for selected sets of elements process of improvement had started with the use of the same observations). ...

... Tables for transformation from sidereal to universal time scale. Explanations. This page contains three little tables headed Hours Minutes Seconds respectively. Each the table have two columns: first of them is input column where time in whole time units of sidereal time is given, and second of them is output column where hours:minutes:seconds of universal time is presented. ... Example: transform 02 h 12 m 22.00 s from sidereal to universal time. ...

... It may be added, subtracted, divided or multiplied in any way appropriate for ordinary numbers. A mathematical relationship involving known numbers (like 25 or 40) and unknown ones (like x ) is known as an equation . ... To get a solution, one must replace the given equation (or equations) with others, containing the same information but cleaner in appearance. ... If you have an equation and modify both its sides in exactly the same way , what you get is also a valid equation. ...
