- DiFX-2.4 or above
- GSL
- GSLCBLAS
- automake autoconf libtool
Limitations:
- 2-bits sampling
- Only generate single-thread multi-channel VDIF
- Default SEFD for 3 antennas
- VDIF packet of all antennas need to repsent the same time length
- $ libtoolize --force
- $ aclocal -I m4
- $ autoheader
- $ automake --force-missing --add-missing
- $ autoconf
- $ ./configure --prefix=$HOME
- $ make
- $ make install
- source DiFX setup.bash file
- source HOPS hops.bash file
- 'datasim --help' shows a list of possible options
- generate v2d and VEX file: './genv2dvex.sh exp_dir input'
- in the directory of the generated v2d and VEX file, create simulated .vdif data: 'datasim -f 100 -s 1000,2000,3000 -d 12345 datasim_7004.input' where -f is the source flux density, -s is a list of antenna SEFDs, -d is the random number seed
