Detailed Description

MIRIAD dataset casacore::MeasurementSet filler.

Derived from carmafiller.

Despite that this program is written in C++ and uses classes, it is really a set of routines manipulating a huge common block.....

Acknowledgement: this program was originally cloned off uvfitsfiller.cc whose code is now in MSFitsInput.cc Ray Plante wrote the other filler, with which we had some cross talk

Limitations, Caveats and Remaining ToDo's

does not apply the various (miriad) complex gain corrections (uvcat and friends should be used for that in miriad, it would be silly to duplicate that code here)
this code won't run if casacore::Double!=double or casacore::Float!=float or casacore::Int!=int On some future 64bit machines this may cause problems?
CARMA type arrays when dishes are not the same size
do not mix arrays from different telescopes (e.g. BIMA and ATCA) but it should handle different configurations (ARRAYs) of the same instrument
handle multiple array configuration datasets that were UVCAT'ed (needs to count antennae up at each array configuration)
true miriad storage manager ?
check UV override, is that being handled transparently?
spectral windows layout (code present, fix table access descriptors) CHECK: what happens if e.g. uvcat does some line= preprocessing
correct restfreq's in source tables that relate to the spectral windows (this code currently coredumps)
make win=,narrow=,wide=0 cause non of them to be written in that selection
add weather table
although no more wides are written, there is a way to make a small MS from the wides only by preprocessing in miriad, but conceivably could be done here as well?? – except the narrow= keyword seems to write files that suffer from the casacore::Table array conformance error

Todo: to deal with multiple zoom setups (freq changes), we need to track which spectral windows each source appears to make a proper source table indexed by source id and spw id

History: Spring 1997: written (cloned off uvfitsfiller) Peter Teuben July 1997: Y2K, fixed table-interface PJT Dec 1997: fixed wideband only data (e.g. uvgen) PJT ??? somebody fixed up this code for some new release ??? May 2000: fixed up for various new AIPS++ conventions PJT and added multi-source & field PJT Sep 2000: development now on linux, converted to OldMS PJT Dec 2000: casacore::Conversion to casacore::MS (MS2) PJT typical compile time: (P600/256M/15MBps HD: 36") typical 3c273 conversion time: 2.6" (5.3->11.3 MB) Cf. that to "uvio" processing time, which runs at disk I/O speed (15 MB/s on the beforementioned laptop) Jan-Feb 2001: window layout, restfreq's and various things to get msmultiscale to work; added some syscal support PJT April 2001: final cleanup for the 1.5 AIPS++ release - PJT [note that from this moment on bimafiller is for experimental use and deprecated, the new version will be called 'mirfiller' Oct 2001: mirlib changed location Sep 2009: revived in CASA, added various tables for CARMA also renamed from bimafiller to carmafiller Sep 2011: initial release Mar 2013: Rename to importmiriad and make it work for ATCA CABB data (more channels, windows and 4 pols) MHW May 2014: Fix some compiler warnings, add TOPO option MHW Jul 2015: Cope with data with changing freq setups,e.g., CABB zoom data with multiple sources MHW Jan 2016 Turn from standalone app into tool+task MHW

a placeholder for the MIRIAD spectral window configuration see also the MIRIAD programmers guide, and its appendix on UV Variables for CARMA we have MAXWIN = MAXWIDE (16 normally, 6 in 2006-2009, more later) narrow band (plus MAXWIDE space to point into the wide band data too)
