0.1.115 sdscaleold
Requires:
Synopsis
ASAP SD task [DEPRECATED]: Scale the sd spectra
Description
### DEPRECATION WARNING
#################################################
This task will be removed in CASA 5.1. The functionality of this task with
MeasurementSet format is replicated with gencal and applycal, and with
CASA image format is replicated with immath.
#########################################################################
Task sdscaleold performs scaling of single-dish spectra by scaling factor given
by parameter named factor. By setting scaletsys = True, associated Tsys is
also scaled.
Arguments
Inputs |

infile |
| name of input SD dataset

| select an antenna name or ID, e.g. ’PM03’ (only effective
for MS input)

scaletsys |
| scaling of associated Tsys
| |
| allowed: | bool |

Example
------------------
Keyword arguments
------------------
infile -- name of input SD dataset
antenna -- select an antenna name or ID
default: 0
example: ’PM03’
NOTE this parameter is effective only for MS input
factor -- scaling factor. float, one- or two-dimensional float list,
or filename storing scaling factor are acceptable
default: 1.0 (no scaling)
example: see description below
scaletsys -- scaling of associated Tsys
options: (bool) True, False
default: True
outfile -- name of output file
default: outfile=’’ (<infile>_scaled<factor>)
example: ’scaled.asap’
overwrite -- overwrite the output file if already exists
options: (bool) True,False
default: False
NOTE this parameter is ignored when outform=’ASCII’
verbose -- Print verbose log messages. If True, Tsys values before
(and after) scaling are printed to logger.
options: (bool) True, False
default: True

DESCRIPTION
-----------
Task sdscaleold performs scaling of single-dish spectra.
Associated Tsys is also scaled if scaletsys is True.
Tsys informations are written in the casalogger and they are
automatically stored in ’casapy.log’.
The infile can be any of ASAP, MS, SDFITS, or RPFITS format.
If outfile name is given or outfile=’’(default), the scaled data
is written to a new file with the same format as the input data
(Note: in case of the RPFITS format input data, it will be written
to SDFITS format).
The scaling factor, factor, accepts both scalar type and list
type value. The list must be one or two dimensional. If factor is
one dimensional, its length must coincide with a number of spectral
channel. If factor is two dimensional, its shape must be
(n, 1) or (n, m), where n is a number of spectrum, while m is a
number of channel for each spcetum. m can be variable for each
spectrum. In addition, the factor can be an ASCII filename that
stores a space-separated list of scaling factor consisting of
adequate number of rows and columns. For example, if the contents
of input ASCII file is shown as,
0.5 0.3 0.2
1.0 0.2 0.9
it is interpreted as a list [[0.5, 0.3, 0.2],[1.0, 0.2, 0.9]].
-------
WARNING
-------
For the GBT raw SDFITS format data as input:
SDtasks are able to handle GBT raw SDFITS format data since the
data filler is available. However, the functionality is not well
tested yet, so that there may be unknown bugs.
