These are the identity of the object measured; the identity of the bandpass in which the measurement was made; the time of the observation; and, for integration-type measurements, the duration of the integration. Table <A HREF="node636.html#tbl:basic-obs-cols">I.17</A> describes the basic table-file columns in detail. <P> <BR><HR> <!--Table of Child-Links--> <A NAME="CHILD_LINKS"> </A> <UL> <LI><A NAME="tex2html9434" HREF="node635.html">What was the measurement?</A> <LI><A NAME="tex2html9435" HREF="node636.html">What was measured?</A> <LI><A NAME="tex2html9436" HREF="node637.html">Bandpass and detector identification</A> <LI><A NAME="tex2html9437" HREF="node638.html">Timing information</A> <LI><A NAME="tex2html9438" HREF="node639.html">Comment field</A> </UL> <!--End of Table of Child-Links--> <BR><HR> <ADDRESS> <I>Petra Nass</I> <BR><I>1999-06-15</I> </ADDRESS> </BODY> </HTML>
