There is some information connected with individual passbands that can naturally be stored in tabular form: the codes used for filters, and the names of the bands, for example. But each particular type of detector has a different set of characteristics, which in turn require different sets of supplementary data. Furthermore, there are distinct modes of operation peculiar to each type: we need dead-time information about photomultipliers only when they are used as pulse-generators, not in DC photometry or charge integration. <P> <BR><HR> <!--Table of Child-Links--> <A NAME="CHILD_LINKS"> </A> <UL> <LI><A NAME="tex2html9065" HREF="node606.html">Storage format</A> <LI><A NAME="tex2html9066" HREF="node607.html">General instrumental information</A> <LI><A NAME="tex2html9067" HREF="node608.html">Passbands</A> <UL> <LI><A NAME="tex2html9068" HREF="node609.html">Columns BAND and NBAND</A> <LI><A NAME="tex2html9069" HREF="node610.html">Column FILTCODE_<B>n</B></A> <LI><A NAME="tex2html9070" HREF="node611.html">Column NDVALUE</A> <LI><A NAME="tex2html9071" HREF="node612.html">Column NDETUSED</A> <LI><A NAME="tex2html9072" HREF="node613.html">Columns REDLEAK, RLTYPE, and MAKER</A> </UL> <LI><A NAME="tex2html9073" HREF="node614.html">Instrument descriptors</A> <UL> <LI><A NAME="tex2html9074" HREF="node615.html">Filter descriptors</A> <LI><A NAME="tex2html9075" HREF="node616.html">Descriptor <B>NFILTCAR</B></A> <LI><A NAME="tex2html9076" HREF="node617.html">Character descriptor FILTCAT</A> <LI><A NAME="tex2html9077" HREF="node618.html">Character descriptor FILTSTAT</A> </UL> <LI><A NAME="tex2html9078" HREF="node619.html">Detectors</A> <UL> <LI><A NAME="tex2html9079" HREF="node620.html">Columns NDET and DETNAME</A> <LI><A NAME="tex2html9080" HREF="node621.html">Column DETCODE</A> <LI><A NAME="tex2html9081" HREF="node622.html">Column DET</A> <LI><A NAME="tex2html9082" HREF="node623.html">Photomultipliers: DET=<TT>PMT</TT></A> <LI><A NAME="tex2html9083" HREF="node624.html">Column COOLING</A> <LI><A NAME="tex2html9084" HREF="node625.html">Silicon photodiodes and CCDs: DET=<TT>SILICON</TT></A> <LI><A NAME="tex2html9085" HREF="node626.html">Other detectors: DET=<TT>OTHER</TT></A> </UL> <LI><A NAME="tex2html9086" HREF="node627.html">Telescope optics</A> <LI><A NAME="tex2html9087" HREF="node628.html">Sample instrument files</A> <UL> <LI><A NAME="tex2html9088" HREF="node629.html">A simple photometer</A> <LI><A NAME="tex2html9089" HREF="node630.html">A modern single-channel photometer</A> <LI><A NAME="tex2html9090" HREF="node631.html">A modern two-channel photometer</A> <LI><A NAME="tex2html9091" HREF="node632.html">CCD photometry</A> </UL></UL> <!--End of Table of Child-Links--> <BR><HR> <ADDRESS> <I>Petra Nass</I> <BR><I>1999-06-15</I> </ADDRESS> </BODY> </HTML>
