The apply_to_all
step is designed for multi-phase centre VLBI observations only and is to cast the calibration from the previous steps to all of the other phase centres. This step will also apply a nominal primary beam correction to these data. There are multiple options available
"apply_to_all":{
"target_path" : "/Users/jackradcliffe/Documents/BD228L/target_files", #path to the fitsidi files of the phase centres
"target_outpath" : "/Users/jackradcliffe/Documents/BD228L/calibrated", #path to where the calibrated data should be stored
"tar_output" : true, #if true, tar the calibrated products (uses gzip compression)
"tar_ms_only" : true, #if true and "tar_output=true" only tar the measurement set (useful for inspecting images quickly)
"pbcor":{
"run" : true, #run primary beam correction
"implementation": "uvcorr", #type of primary beam correction (see below for options)
"vex_file" : "", #vex file name+path (will override pointing_centre)
"pointing_centre" : ["10h01m22.8650000s","+2d19m28.333s"], #pointing centre of observations in CASA format
"backup_caltables" : true #add pbcor tables to the tar bundle of calibration tables
},
"image_target":{
"run" : true, #if true, image targets
"imsize" : [1024,1024] #image size
},
"hpc_options":{
"partition" : "default",
"walltime" : "default",
"nodes" : -1,
"cpus" : -1,
"mpiprocs" : -1,
"nodetype" : "default",
"max_jobs" : 24 #important for PBS/slurm runs. Determines how many concurrent jobs can run at once.
}
The primary beam correction has three different implementations to correct, and two different ways of setting the pointing centres. We first begin with the modes,
