DIGITAL WDC EXCHANGE FORMAT . FOR OBSERVATORY 1.0 MINUTE VALUES 1. ... DATA-1 .. DATA-60 are 1-minute values of the given element for that hour. ... Typically, digital 1-minute values received by WDCs from organizations operating automatic magnetic observatory instruments are averages of more frequendy sampled values, e.g. 10-second point samples. ... If the method used to obtain 1-minute average values is important to a user, the WDC will assist in determining the exact procedure applied. ...

CFITSIO Interface Library CFITSIO is a library of ANSI C routines for reading and writing FITS format data files. ... The CFITSIO library is built on Unix systems by typing: > ./configure [--prefix=/target/installation/path] > make (or 'make shared') > make install (this step is optional) at the operating system prompt. The configure command customizes the Makefile for the particular system, then the `make' command compiles the source files and builds the library. ...
