smalod - Convert an Sma archive data (Caltech MIR) into Miriad uv format  




data transfer  


SMALOD is a MIRIAD task, which converts the standard SMA data format to Miriad format.  


in Name of the input MIR file.
There is no default.
Name of the output Miriad uv data-set. No default.
select data from one of the dual receivers/IFs: rxif=-1 for the 1st rxif band; rxif=-2 for the 2nd rxif band.

select the data based on receiver id: for data taken after 2006-12-28 -- rxif=0 for receiver id = 0 -> 230 GHz band; rxif=1 for receiver id = 1 -> 340 GHz band; rxif=2 for receiver id = 2 -> 400 GHz band; rxif=3 for receiver id = 3 -> 690 GHz band; for data taken before 2006-12-28 -- rxif=0 for receiver id = 0 -> 230 GHz band; rxif=1 for receiver id = 1 -> 340 GHz band; rxif=2 for receiver id = 2 -> 690 GHz band.

The default is rxif=-1 or the 1st rxif band.

The rest frequency, in GHz, for line observations. By default, the value in the MIR file is used. we are cosidering to support the following functions: Giving a value for the "restfreq" parameter overrides the MIR file value. If you do set this parameter, you MUST give the same number of values as the number of IFs written out. A value of 0 is used for a continuum observation. For example, if you have two IFs, the first of which is CO(3-2), and the second is continuum, use restfreq=345.795991,0
The radial velocity of source in km/s w.r.t. the LSR or the barycenter, which was included in the online Doppler track. The velocity reference frame can be selected in options. Positive velocity is away from observer. Default is zero.
The reference antenna. Default is 6. The reference antenna needs to be present while the antenna positions are being decoded from baseline vectors stored in SMA MIR data. The geocentrical coordinates for the antennas can be retrieved from SMA sybase. For double checking the antenna positions, one can login to (IP: and use the following command: dBValue -d hal9000-newdds -v dsm_dds_hal_x_v11_d -t "2004-11-16 00:00:00" dBValue -d hal9000-newdds -v dsm_dds_hal_y_v11_d -t "2004-11-16 00:00:00" dBValue -d hal9000-newdds -v dsm_dds_hal_z_v11_d -t "2004-11-16 00:00:00" If the reference antenna is not the default value 6, one may need to give the reference antenna here.
           direction of a source, w.r.t. the barycenter. 
           Default uses the on-line values.
           direction of a source, w.r.t. the LSR. 
           Default uses the on-line values.
           The above two options might be applied only when
           the chunk frequency stored in the SMA raw data
           corresponds to the true Doppler tracked sky frequency
           or no online correction to the frequency has been
           labelled as XX. Default in options for polarization 
           is nopol.
           receivers and waveplates for each antenna. For the 
           circular polarization data observed before 2005-06-10, 
           the polarization states are swapped by the default 
           (RR<->LL, RL<->LR or -1 <-> -2, -3 <-> -4).

           Defaults assume that non-polarization state is assigned.
           only for the first three blocks (1 2 3).

           data with source name "target" and/or "unknown".
           The default is to handle multiple correlator configuration. 
           For data taken after 2006-5-12, the default 
           will properly handle the hybrid high spectral 
           resolution mode, allowing presence of empty 
           spectral windows (chunks).
