| - | PSRIX2 with the CX receiver makes use of two ROACH2 boards to digitally process two 2GHz bands. The data are written in an intermediate form. There is a code (thanks Gregory!) to convert and merge the ROACH2 outputs to PSRFITS format that can be subsequently folded with ''fold_psrfits'' or searched. Note that ''dspsr'' will not fold 8-bit 4-pol data properly, and hence need to use fold_psrfits. | + | PSRIX2 with the CX receiver makes use of two ROACH2 boards to digitally process two 2GHz bands.

| - | ''paf0:> fold_psrfits -P 0355+54.par -t 10 roach2_B0355+54_59353_6000_000*.fits'' will generate a file ''roach2_B0355+54_59353_53611_0001.fits''. Nite that you have to provide an ephemeris to ''fold_psrfits''. The output can be viewed and manipulated with PSRCHIVE. | + | ''paf0:> fold_psrfits -P 0355+54.par -t 10 roach2_B0355+54_59353_6000_000*.fits'' will generate a file ''roach2_B0355+54_59353_53611_0001.fits''.
