The results structure in the Specdre Extension v.0.7

• .RESULTS.DATA_ARRAY and .RESULTS.VARIANCE are _REAL or _DOUBLE array structures which default to bad values. They have one axis more than <myndf>: the spectroscopic axis is skipped; instead new first and second axes are inserted. The first axis counts the fit parameters up to the maximum (tnpar). The second axis is of length 1 and may be used in future. All further axes are of the same length as the corresponding non-spectroscopic axes in <myndf>.

• .RESULTS.MORE.LINENAME is a _CHAR*32 vector which defaults to `unidentified component'. There is one element for each component. Its value is a spectroscopist's description of the component, such as `[OIII] 5007 v-comp #1', `12CO J=1-0', `nebulium', `5500 K black body'. It is essential that the strings are of length 32.

• .RESULTS.MORE.LABFREQ is a _REAL or _DOUBLE vector which defaults to bad values. There is one element for each component. The value is the laboratory frequency of the transition. The units used are the ones stored in .FREQUNIT. The laboratory frequency is the frequency as observed in the emitter's rest frame. The meaning of this frequency is similar to that of .FREQREF in that the laboratory frequency of a transition is a useful value for the reference frequency of the velocity or redshift axis. The difference is that each component fitted may or may not have its own laboratory frequency. .FREQREF will usually be a copy of one of the elements of .RESULTS.MORE.LABFREQ.

• .RESULTS.MORE.COMPTYPE is a _CHAR*32 vector which defaults to `unknown function'. There is one element for each component. Its value is a mathematician's description of the component, such as `Gauss', `triangle', `Lorentz-Gauss', `Voigt', `polynomial', `Chebyshev series', `sine'. It is essential that the strings are of length 32.

• .RESULTS.MORE.NPARA is an _INTEGER vector defaulting to INT(tnpar/ncomp). There is one element for each component. Its value is the number of parameters stored for that component. When more components are added to an existing .RESULTS structure, then the new components are allocated by default INT(( tnpar - tnpar_old) / (ncomp - ncomp_old)) parameters. The numbers of parameters must be greater than or equal to zero.

• .RESULTS.MORE.MASKL and .RESULTS.MORE.MASKR are _REAL or _DOUBLE vectors which default to bad values; both are of the same type. There is one element in either vector for each component. A component comp is evaluated according to type and parameters in the range of spectroscopic values between maskl(comp) and maskr(comp). The component is assumed to be zero outside this interval. Bad values indicate that the range is not restricted.

• .RESULTS.MORE.PARATYPE is a _CHAR*32 vector which defaults to `unknown parameter'. There is one element for each parameter. Its value is a mathematician's description of the parameter. A Gauss profile might be specified by parameters `centre', `peak', `sigma width', `integral'. It is essential that the strings are of length 32.

It should be noted that there exist no rules about how to store certain components, such as `A Gauss profile must be called Gauss and have parameters such-and-such'. What is stored should be described by the strings so that a human reader knows what it is all about. This does not prevent pairs of applications from storing and retrieving components if they use the strings in a consistent way. The documentation of any application that writes or reads results should specify what strings are written or recognised.
