calanalysis.get - Function
2.1.2 Return the calibration data.
Description
This member function returns the calibration data.
Arguments
Inputs |
| ||
field |
| The python comma-delimited string or list of strings
containing the field names or numbers. The default is ””
(all fields).
| |
| allowed: | variant | |
| Default: | ||
antenna |
| The python comma-delimited string or list of strings
containing the antenna 1s and antenna 2s. The default
is ”” (all antenna 1s and antenna 2s).
| |
| allowed: | variant | |
| Default: | ||
timerange |
| The python list of floats of length two containing the
start and stop times (in MJD seconds). The default is []
(the minimum start time and the maximum stop time).
| |
| allowed: | variant |
|
| Default: |
| |
spw |
| The python comma-delimited string containing the
spectral window names and numbers along with their
channel numbers. The default is ”” (all spectral windows
and channels).
| |
| allowed: | variant | |
| Default: | ||
feed |
| The python comma-delimited string or list of strings
containing the feeds. The default is ”” (all feeds).
| |
| allowed: | variant | |
| Default: | ||
axis |
| The python string containing the user-specified
iteration axis. The allowed values are ”TIME” and
”FREQ”. The default is ”” (”FREQ”).
| |
| allowed: | string |
|
| Default: | TIME | |
ap |
| The python string which determines whether complex
gains are converted to amplitudes or phases. The allowed
values are ”AMPLITUDE” and ”PHASE”. The default
is ”” (”AMPLITUDE”). This parameter is ignored when
the ”gain” values in the calibration table are real.
| |
| allowed: | string |
|
| Default: | AMPLITUDE |
|
norm |
| The python boolean which determines whether the
amplitudes are normalized along each non-iteration axis.
The default is False. This parameter is ignored when
the ”gain” values in the calibration table are real or
ap=”PHASE”.
| |
| allowed: | boolean |
|
| Default: | false |
|
unwrap |
| The python boolean which determines whether the
phases are unwrapped along each non-iteration axis.
The default is False. This parameter is ignored when
the ”gain” values in the calibration table are real or
ap=”AMPLITUDE”.
| |
| allowed: | boolean |
|
| Default: | false |
|
jumpmax |
| The python float which determines the maximum phase
jump near +/- PI before unwrapping is performed. E.g.,
jumpmax = 0.1. The default is 0.0. It is ignored if the
”gain” values in the calibration table are real or ap =
”AMPLITUDE”. If the non-iteration axis is frequency:
1) if jumpmax == 0.0, use fringe fitting (only available
when the non-iteration axis is time); 2) if jumpmax !=
0.0, use simple unwrapping (same algorithm as used
when the non-iteration axis is time or frequency).
| |
| allowed: | double |
|
| Default: | 0.0 |
|
record
Example
# All data limited only by the spectral window and channel input
data = ca.get( spw="0:4~15,1,2:10~20" )
