These parameters are stored in keywords and will be use as default values for subsequent OPTOPUS commands. If an OPTOPUS command the default value is not used the command will, in addition to actual OPTOPUS operation, also overwrite the setting of this parameter and hence will change the default value.<BLOCKQUOTE> <TT><TT>SET/OPTOPUS OLDEQ=1950.0 ! set the equinox</TT> <BR> <TT>CREATE/OPTOPUS mydata mytable ? 2000.0 ! use another equinox</TT> <BR> <TT>SHOW/OPTOPUS ! equinox value is now 2000.0</TT></TT></BLOCKQUOTE> <BR> <DIV ALIGN="CENTER"><A NAME="29454"> </A> <TABLE> <CAPTION><STRONG>Table H.5:</STRONG> Command parameters</CAPTION> <TR><TD> <DIV ALIGN="CENTER"> <TABLE CELLPADDING=3 BORDER="1" ALIGN="CENTER"> <TR><TD ALIGN="CENTER" COLSPAN=2><TT> CREATE/OPTOPUS</TT></TD> </TR> <TR><TH ALIGN="LEFT"><B>Parameter </B></TH> <TD ALIGN="LEFT" VALIGN="TOP" WIDTH=12><B>Description </B></TD> </TR> <TR><TD ALIGN="LEFT"><TT> OLDEQ</TT></TD> <TD ALIGN="LEFT" VALIGN="TOP" WIDTH=12>Equinox of RA and DEC coordinates of objects and guidestars in input table.
