If it is routinely available for every measurement, it should go in a column labelled PRESSURE, with the SI unit kPa. Note that pressures read from aneroid (dial-type) barometers are not very accurate, and probably should not be used. Only absolute pressures should be recorded, <I>not</I> values ``corrected to sea level''. <P> <BR> <DIV ALIGN="CENTER"><A NAME="30712"> </A> <TABLE> <CAPTION><STRONG>Table:</STRONG> Other column specifications for observational-data tables</CAPTION> <TR><TD> <DIV ALIGN="CENTER"> <TABLE CELLPADDING=3 BORDER="1" ALIGN="CENTER"> <TR><TD ALIGN="LEFT">Column Label</TD> <TD ALIGN="CENTER">Contents</TD> <TD ALIGN="CENTER">Units</TD> <TD ALIGN="LEFT">Variable Type</TD> <TD ALIGN="LEFT">Format</TD> </TR> <TR><TD ALIGN="LEFT"><TT> RAWMAG</TT></TD> <TD ALIGN="CENTER">object measurement</TD> <TD ALIGN="CENTER">magnitudes</TD> <TD ALIGN="LEFT">R*4 real</TD> <TD ALIGN="LEFT">Fw.d</TD> </TR> <TR><TD ALIGN="LEFT"><TT> SKYRA</TT></TD> <TD ALIGN="CENTER">sky measurement position</TD> <TD ALIGN="CENTER">degrees</TD> <TD ALIGN="LEFT">R*4 real</TD> <TD ALIGN="LEFT">F4.1</TD> </TR> <TR><TD ALIGN="LEFT"><TT> SKYDEC</TT></TD> <TD ALIGN="CENTER">sky measurement position</TD> <TD ALIGN="CENTER">degrees</TD> <TD ALIGN="LEFT">R*4 real</TD> <TD ALIGN="LEFT">F4.1</TD> </TR> <TR><TD ALIGN="LEFT"><TT> SKYOFFSETALT</TT></TD> <TD ALIGN="CENTER">sky measurement position</TD> <TD ALIGN="CENTER">arcsec</TD> <TD ALIGN="LEFT">R*4 real</TD> <TD ALIGN="LEFT">F4.0</TD> </TR> <TR><TD ALIGN="LEFT"><TT> SKYOFFSETAZ</TT></TD> <TD ALIGN="CENTER">sky measurement position</TD> <TD ALIGN="CENTER">arcsec</TD> <TD ALIGN="LEFT">R*4 real</TD> <TD ALIGN="LEFT">F4.0</TD> </TR> <TR><TD ALIGN="LEFT"><TT> FILTTEMP</TT></TD> <TD ALIGN="CENTER">filter temperature</TD> <TD ALIGN="CENTER">see text</TD> <TD ALIGN="LEFT">R*4 real</TD> <TD ALIGN="LEFT">F4.1</TD> </TR> <TR><TD ALIGN="LEFT"><TT> DETTEMP</TT></TD> <TD ALIGN="CENTER">detector temperature</TD> <TD ALIGN="CENTER">see text</TD> <TD ALIGN="LEFT">R*4 real</TD> <TD ALIGN="LEFT">F4.1</TD> </TR> <TR><TD ALIGN="LEFT"><TT> DOMETEMP</TT></TD> <TD ALIGN="CENTER">dome temperature</TD> <TD ALIGN="CENTER">see text</TD> <TD ALIGN="LEFT">R*4 real</TD> <TD ALIGN="LEFT">F4.1</TD> </TR> <TR><TD ALIGN="LEFT"><TT> RELHUM</TT></TD> <TD ALIGN="CENTER">relative humidity</TD> <TD ALIGN="CENTER">per cent</TD> <TD ALIGN="LEFT">R*4 real</TD> <TD ALIGN="LEFT">F4.1</TD> </TR> <TR><TD ALIGN="LEFT"><TT> PRESSURE</TT></TD> <TD ALIGN="CENTER">atmos. pressure</TD> <TD ALIGN="CENTER">kPa</TD> <TD ALIGN="LEFT">R*4 real</TD> <TD ALIGN="LEFT">F4.1</TD> </TR> <TR><TD ALIGN="LEFT"><TT> DIAPHRAGM</TT></TD> <TD ALIGN="CENTER">field stop code</TD> <TD ALIGN="CENTER"> </TD> <TD ALIGN="LEFT">C*4 string</TD> <TD ALIGN="LEFT">A4</TD> </TR> <TR><TD ALIGN="LEFT"><TT> PMTVOLTS</TT></TD> <TD ALIGN="CENTER">PMT high voltage</TD> <TD ALIGN="CENTER"> </TD> <TD ALIGN="LEFT">C*4 string</TD> <TD ALIGN="LEFT">A4</TD> </TR> <TR><TD ALIGN="LEFT"><TT> GENEVA_Q</TT></TD> <TD ALIGN="CENTER">Geneva Q parameter</TD> <TD ALIGN="CENTER"> </TD> <TD ALIGN="LEFT">R*4 real</TD> <TD ALIGN="LEFT">E9.2</TD> </TR> <TR><TD ALIGN="LEFT"><TT> GENEVA_R</TT></TD> <TD ALIGN="CENTER">Geneva R parameter</TD> <TD ALIGN="CENTER"> </TD> <TD ALIGN="LEFT">R*4 real</TD> <TD ALIGN="LEFT">E9.2</TD> </TR> <TR><TD ALIGN="LEFT"><TT> GENEVA_G</TT></TD> <TD ALIGN="CENTER">Geneva G parameter</TD> <TD ALIGN="CENTER"> </TD> <TD ALIGN="LEFT">R*4 real</TD> <TD ALIGN="LEFT">E9.2</TD> </TR> <TR><TD ALIGN="LEFT"><TT> SEEING</TT></TD> <TD ALIGN="CENTER">seeing value</TD> <TD ALIGN="CENTER">see text</TD> <TD ALIGN="LEFT">C*4 string</TD> <TD ALIGN="LEFT">A4</TD> </TR> <TR><TD ALIGN="LEFT"><TT> ESTERR</TT></TD> <TD ALIGN="CENTER">estimated error</TD> <TD ALIGN="CENTER">see text</TD> <TD ALIGN="LEFT">R*4 real</TD> <TD ALIGN="LEFT">Fw.d</TD> </TR> </TABLE></DIV> <A NAME="tbl:other-obs-cols"> </A></TD></TR> </TABLE> </DIV> <BR> <P> <HR> <!--Navigation Panel--> <A NAME="tex2html9529" HREF="node643.html"> <IMG WIDTH="37" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="next" SRC="icons.gif/next_motif.gif"></A> <A NAME="tex2html9526" HREF="node640.html"> <IMG WIDTH="26" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="up" SRC="icons.gif/up_motif.gif"></A> <A NAME="tex2html9520" HREF="node641.html"> <IMG WIDTH="63" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="previous" SRC="icons.gif/previous_motif.gif"></A> <A NAME="tex2html9528" HREF="node1.html"> <IMG WIDTH="65" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="contents" SRC="icons.gif/contents_motif.gif"></A> <BR> <B> Next:</B> <A NAME="tex2html9530" HREF="node643.html">Measuring aperture</A> <B> Up:</B> <A NAME="tex2html9527" HREF="node640.html">Additional information</A> <B> Previous:</B> <A NAME="tex2html9521" HREF="node641.html">Temperature and humidity data</A> <!--End of Navigation Panel--> <ADDRESS> <I>Petra Nass</I> <BR><I>1999-06-15</I> </ADDRESS> </BODY> </HTML>
