A shoebox full of potentially useful data reduction scripts is listed below. Please contact me if you have any questions, find a bug or even, maybe, find them useful.
- v190 pipeline: A full VLBI pipeline for loading, editing, calibrating and writing out phase-referenced VLBI pulsar observations, using Parseltongue. Could easily be adapted for any phase-referenced observations. At the moment a lot of stuff is hard-coded at the top of the script, but that could be changed easily
- v190 utils: Utility functions needed for the v190 pipeline
- logs2antab: Takes current-format LBA tsys log files and creates a nice antab format file
- Wizardry_correctmodel: Uses the wizardry feature of Parseltongue to difference two DiiFX format delay/uvw files and create a CL table from the differences in the geometric model. The table is attached to an AIPS file, and the AN table, SU table and uvw values in the file are updated - so the CL table must be applied or the data will be inconsistent with the uvw values and the tables.
- Wizardry_correctpropermotion: Uses the wizardry feature of Parseltongue to create a CL table, similar to correctmodel above, which accounts for the proper motion of a high-velocity object like a pulsar over the course of a single observation.
- Wizardry_scintamp: Uses the wizardry feature of Parseltongue to create an SN table which accounts for the effects of scintillation, assuming a point source (like a pulsar). Basically tries to normalise the visibility amplitudes to a constant value, and adjusts the weights to be proportional 1/(normalisation factor)^2
- Wizardry_selfcalsnfix: Uses the wizardry feature of Parseltongue, along with Emil Lenc's cordump feature in difmap to create an SN table containing selfcal corrections, when some antennas have additional IFs but the additional IFs are not present on enough baselines to calculate closure amplitudes
- Ionex_movie: Creates a movie showing TEC from an ionex-style file
- Jmfit_from_file: Models a point source in difmap and creates an image, which is loaded into AIPS and fit for position in the image plane using JMFIT
- Make_fit_plot: Creates a plot of pulsar motion by fitting with pmpar and plotting the predictions and observations using gnuplot. Produces colour or grayscale postscript output
- Wizardry_weightfix: Fixes the weights of a source by scaling by the predicted baseline sensitivity
