Build a GILDAS table from current index entries. No gridding is done.
This table may be then regridded on a Regular Grid to build a datacube
for further use in GREG.
OLD Append to table 'filename'
NEW Create a new table
/MATH
Compute one or more mathematical expressions instead of storing a
spectrum. See subtopic /MATH for details.
/RANGE
By default, the whole X axis is stored in the GILDAS table. A range
can be imposed, in which case the unit must be specified.
/RESAMPLE
By default, the spectra are resampled, on-the-fly while building the
TABLE, on the first spectrum X axis. This option allows to enforce
that resampling is done on the given X axis. See HELP RESAMPLE for
possible uses and caveats.
/LIKE
Same as /RESAMPLE, except that the X axis is guessed from a refer-
ence GDF file (can be a cube or a UV table).
/FFT
To specify that resampling is done in time domain.
/FREQUENCY
To change the line name and/or the rest frequency.
/WEIGHT
Specify which weight is to be saved in the dedicated column in the
output table. Default is ruled by SET WEIGHT.
/NASMYTH
Specify that the spectra offsets (X and Y leading columns) written
to the table should be rotated to offsets expressed in the Nasmyth
plane. Beware it is the responsibility of the user to remember if
this conversion was applied or not, as the data format does not keep
track of it.
/NOCHECK
By default, the consistency of the index is checked against SOURCE,
POSITION, LINE and SPECTROSCOPY parameters (see LAS\CONSISTENCY) be-
fore building the table. If the SPECTROSCOPY section appears incon-
sistent, the spectra are resampled on-the-fly on the first spectrum
X axis. Other sources of inconsistency are not recoverable and the
table is not built. This option without keyword allows to disable
all consistency checks. With keyword(s), disable the corresponding
checks.
Warnings:
1. /MATH, /RANGE, /RESAMPLE and /LIKE are exclusive
2. Continuum data not supported
