integ
NAME
integ - integrate profiles into one
SYNOPSIS
integ
[ -scn default_name ]
[ -weighted | -uniform | -rms ]
DESCRIPTION
The command integrates several profiles stored in .scn files.
The input .scn files are assigned in .sdb flow.
Only profiles with "good" flags are processed.
According to definition of sdb flow
a line with a character "!" at the first column is "sdb command",
and a line with "#" at the first column is "sdb comment".
The command integrates all "good" profiles between two "!integ" command
lines; each scn block separated by "!integ" command line is integrated
separately.
Additional "!integ" command lines are assumed at just before the first "scn"
and just before the last line, even if either is not there.
The last line of sdb flow must be "!end" command.
The command simply integrates all profiles channel by channel.
In some cases this gives physically meaningless profile.
To adjust this, you should apply smooth command.
If loaded profile is not the same velocity-channel relation and/or
position on sky as the first one, the command shows warnig massages
in the command shell window. But the integration is done.
FILTER TYPE
.sdb | integ | .scn
OPTIONS
- -scn default_name
-
- -weighted | -uniform | -rms
- Weight for each profile data.
With "-weighted" the command integrates the profiles using the weight value
stored in each profile data.
With "-uniform" the command integrates all profile data with
equal weighting.
With "-rms" the command integrates the profiles using the rms
stored in each profile data, acutally 1/(rms*rms) weighting.
DEFAULTS
- -scn default -weighted -prm integ.prm
SEE ALSO
sdbflag, scnflag, sdbselect, smooth, .sdb, .scn
BUGS
- No .sdb command is not yet supported.
- Even unintegrable profiles are integrated channel by channel.
In such case you should apply the smooth command
for .scn data. This should be automatically applied but is not.
