0.1.57 imreframe
Requires:
Synopsis
Change the frame in which the image reports its spectral values
Arguments
Inputs |
| ||
imagename |
| Name of the input image
| |
| allowed: | string |
|
| Default: |
| |
output |
| Name of the output image; ” => modify input image
| |
| allowed: | string |
|
| Default: |
| |
outframe |
| Spectral frame in which the frequency or velocity values
will be reported by default
| |
| allowed: | string |
|
| Default: | lsrk |
|
epoch |
| Epoch to be associated with this image e.g
’2000/12/25/18:30:00.10’
| |
| allowed: | string |
|
| Default: |
|
|
restfreq |
| restfrequency to use for velocity values (e.g ”1.420GHz”
for the HI line)
| |
| allowed: | string |
|
| Default: |
|
|
void
Example
imagename -- name of casa image file to process on
output -- name of output image ’’ means modify the input image itself
default: ’’;
outframe -- new spectral frame in which the frequency or
velocity will be reported for.
Options: ’lsrk’,’lsrd’,’bary’,’geo’,’topo’,’galacto’,
’lgroup’,’cmb’
default: ’lsrk’
>>>
epoch -- when outframe is ’topo’ or ’geo’ a time in UTC is needed
to decide when to do the frequency conversion. ’’ is to use
the epoch of the input image
default= ’’
restfreq -- Specify rest frequency to use for output image
default=’’; ’’ means use the restfrequency already in input image
For example for
NH_3 (1,1) put restfreq=’23.694496GHz’
