LuMP Processing

An alternative recording method for some observations is with the LuMP software from MPIfRA. It has been used in the past for coordinated observations with FR606 and at the request of observers from the UK and Poland.

Any DSPSR sub-program (dspsr, digifil, digifits) can be used to process a LuMP observation, but each port/process (if using a multi-processed recording mode) must be processed separately and then combined (fils: filmerge, fits/ar: psradd).

So as an example, to process with digifil you may choose to process a set of observations using the command

for file in *.raw; do
	digifil -b-32 -F <NUMCHAN>:D -I 0 -c -set site="I-LOFAR" $file -o $file".fil"
done

filmerge *.raw.fil

To perform coherent dedispersion (-F <CHAN>:D) for a known pulsar target (inside LuMP metadata), without any bandpass/temporal offsets (-I 0 -c), producing a 32-bit output (-b-32) filterbank.
