NAME
msset -- Set entries in a MULTISPEC database
.ih
USAGE
msset image keyword value
.ih
PARAMETERS
.ls image
Image in which the MULTISPEC database entries are to be modified or initialized.
.le
.ls keyword
Keyword for the database entry to be set. The keywords are:
.ls nspectra
Set the number of spectra in the header.
.le
.ls comments
Add comments lines to the database comment block.
.le
.ls x0
Set the spectra positions for the specified sample lines and spectra.
.le
.ls i0
Set the model profile central intensities for the specified sample lines
and spectra.
.le
.ls s0, s1, or s2
Set the gauss5 model shape parameter s0, s1, or s2 for the specified sample
lines and spectra.
.le
.le
.ls value
Value to be used for value input.
.le
.ls lines = "*"
Sample lines to be affected by value input.
.le
.ls spectra = "*"
Spectra to be affected by value input.
.le
.ls read_list = no
If yes use list input and if no use value input.
.le
.ls list = ""
List for list input. See the description below for the appropriate format.
.le
.ih
DESCRIPTION
The entries in a MULTISPEC database associated with the image
are modified or initialized.
The parameters \fIimage\fR, \fIkeyword\fR, and \fIread_list\fR
determine the database to be operated upon, the database entry to
be set, and the input type. There are two forms of input;
list input and value input.
The input type is selected by the boolean parameter
\fIread_list\fR. For list input the parameter \fIlist\fR
is used and for value input the parameter \fIvalue\fR and
possibly the parameters \fIlines\fR and \fIspectra\fR are used.
The required parameters and input formats for the different keywords
are outlined below.
.ls nspectra
For list input the list format is the number of spectra and
for value input the \fIvalue\fR parameter is the number of spectra.
.le
.ls comments
For list input the list format is lines of comments and for value
input \fIvalue\fR parameter is a comment string.
.le
.ls x0, i0, s0, s1, s2
For list input the list format is sample line, spectrum number, and
parameter value
and for value input \fIlines\fR is a range string selecting the
sample lines to be affected, \fIspectra\fR is a range string selecting
the spectra to be affected, and \fIvalue\fR is the value to be set for all
the selected lines and spectra.
.le
.ih
EXAMPLES
To add several comments to the database by query:
.nf
cl> msset image "comments" read_list+
Input list> First comment here.
Input list> Second comment here.
Input list> <eof>
.fi
where <eof> is the end of file character terminating the list.
To set the value of s0 to 1 for all the spectra in sample line 1:
cl> msset image "s0" 1
To set the spectra positions from a list:
cl> msset image "x0" read_list+ list=positionlist
To add a single comment such as in a script:
cl> msset image "comments" "Comment here."
