Responsivities, in amperes per watt, go in a column named <TT>'RESP'</TT>. (Observers who have difficulty converting manufacturers' data from microamperes per microwatt to amperes per watt should be encouraged to take up a less demanding field than photometry.) Alternatively, responsive quantum efficiencies can be put in a column named <TT>'RQE'</TT>; this quantity is dimensionless. All these data are Real*4. The table should contain one character descriptor, named <B>RESPTYPE</B>, whose value is either <TT>'RESP'</TT> or <TT>'RQE'</TT>, to indicate which type of data are tabulated. <P> The remarks made above about the COOLING column apply here also; see the discussions given in connection with PMTs and CCDs. <P> <BR><HR> <ADDRESS> <I>Petra Nass</I> <BR><I>1999-06-15</I> </ADDRESS> </BODY> </HTML>
