difx:difx-todolist-2016
To-Do and Wish List
Before the end of the week
- Clock units in vex2difx
- progress: confirmed even newest FS vex library has no support for sec/sec units
- progress: vex2difx currently behaves ligitimately – no changes required
- plan: Ask Ed to add this.
- VDIF channel order
- progress: complete! Documented that one cannot change to or from VDIF format with .v2d.
- Check put in vex2difx to prevent this.
- Complete!
- Handle >5 EOPs correctly (at least remove the incorrect sliding average code)
- progress: email sent to DAIP regarding AIPS handling…
- Plan: Will be solved in CALC-11. Walter to check how that handles.
- SFXC-DiFX sensitivity question
- progress: likely related to spectral independence and not a DiFX issue
- Plan: Need to look at detections/non-detections.
- zoom band amplitudes
- progress: complete!
- Fix errors caused by strideLength and xmacLength during wideband + zoom band
- progress: stridelength = 0 → automatic calculation
- progress: xmacstride = 0 → automatic calculation
- Plan: consider having value not set == 0.
- Update the pulsar documentation
- progress: complete!
- Finalise the new (open-source) license (and repository?) Prepare a template that everyone can fill in.
- progress: GPLv3 to be recommended
- Make repository available
- Plan: Chris to get password restrictions removed.
- IPP9
- plan: test! (Chris + everybody)
- difx2fits:
- allow files to be mergeable even when inhomogenoues array results in setups for different jobs
- Testing architecture:
- Jenkins. (Matteo, John)
- Make test datasets useable again (v2d files, etc.)
- Documentathon with emphasis on inner workings (all)
- New download procedures, remove CIRA wiki (Cormac)
- Plan: DataSim feature wishlist (all).
High Priority
- Regression testing scripts (AD)
- Plan: Matteo investigate Jenkins
Xcube support (at least one way of getting Xcube data into DiFX) (CP)- Mark6 support (complete getting Mark6 data into DiFX) see difxmark6
- Plan: progressing. Investigate vbsfs.
- Finish/publish data generator for producing test datasets. (NP,ZMZ,ASIAA)
- datasim works
- plan: add to difx build scripts.
- vex2 support (relies on vex2 finalization and some support from field systems)
- document almost complete
- vex parser is almost complete
- Support for $BITSTREAMS largely complete in vex2difx
- Plan: finalise, test
- DBBC3 support
- progress: complete, but untested
- plan: test! (Requires access to some data)
- redirect old CIRA wiki to CSIRO wiki
- Plan: Remove old pages from CIRA wiki
Medium Priority
- GPU acceleration of the DiFX core code
- Add project code to difx messages (JS)
- Add DiFX diagnostics
- Documentation
- Putting doxygen of mpifxcorr source on a webserver (link to this from the DiFX wiki if completed)
- Maintain database of benchmarking results
- at least the regression tests
- Even better, using fake data also
- visplot (CP, JS)
- Investigate sampler stats monitoring (AD/WB/CP)
- subband distribution/parallelisation (with VDIF) (AD/CP)
- replumbing/refactoring vex2difx setup
- Transition to using band centres instead of band edges (WB)
- Parallelised calc server / Efficiency gains in CALC (wait for difxcalc11, which has “native” support and will be easier to parallelise)
- Cleanly separate data format and data source
- difx2vgos? Next generation geodetic output data format support
- A version of polarisation conversion code in the DiFX source codebase
- Option for zero-padded FFT
Low Priority
- evlbi
- reconnection/long term drop-outs (CP)
- reliability with UDP data (CP)
- real-time delay/rate adjustment (CP)
- Store polynomial tau(l, m) generalized delay model in FITS (WB,JM)
- Mixed module and file list on one station
- Check the relative signs of 1-bit / 2-bit unpacking
- IF selection in difx2fits
- addZoomFreq in the SETUP section (applies to all antennas)
- Document Algorithms
- monitoring, etc - (list of error codes) (AD)
- Still produce one FITS file even when there was a clock change during the correlation
- Refactoring the mpifxcorr/mk5daemon libraries and merging functionality
- Move to a compressed text format for pcal files
- Modernize sniffer
- cleanup of DiFX error messages (appropriate verbosity level everywhere)
- eVLBI gui
- Shifted FT (moving channel boundary to edge of band) (AD)
- DiFX2fits uv shifting in trunk (JM/AD)
- Pulsar predictor support in “polyco”
- Get rid of printing to screen in mark5access (change to be called and printed from elsewhere)
- Get Eric to improve AIPS PCAL (multi tone)
Fantasy wishlist
- Choose framework for unit testing. Implement test cases.
- Phased array
- Add per-IF phase polynomial in the calc file (and delay polynomial, too?)
- On-the-fly application of calibration (bandpasses etc) with appropriate accountability
- Space VLBI
- Baseline dependent averaging
- Auditing / refactoring the amplitude scaling
- Restitching contiguous zoom bands into wider bands (e.g. for ALMA)
