hi wang, i can only answer two of your questions:
1) the "corner turner" is also called a "data re-order" or a "matrix transpose". it's job is to change antenna ordered data to frequency ordered data. 2) "miriad" is an open source data reduction software package for radio antenna arrays. e.g. it does post processing convert the data from a correlator into a spectral image. best wishes, dan On Fri, Nov 25, 2022 at 9:37 AM Wang <sandang19990...@gmail.com> wrote: > Hi all， > > I am studying the design of PAPER Correlator. > PAPER Correlator Netcfg - Casper (berkeley.edu) > <https://casper.astro.berkeley.edu/wiki/PAPER_Correlator_Netcfg> > There are some questions about Corner Turner Mode(CTMODE) and MIRIAD > Channel Mapping. > > 8 F engines(CTMODE):The 256 inputs by 1024 channels are presented to the X > engines as exactly that. > 4 F engines(CTMODE):The 128 inputs by 1024 channels are presented to the X > engines as 256 inputs by 512 channels. > ······ > I know that each F engine has 32 inputs, so 8 for 256 and 4 for 128. > But in 'X engine' I don't understand the relationship between input and > channel. > > And，I have a silly question, why is 'Corner Turner' called that? > > The last part is "MIRIAD Channel Mapping". > I don't understand the meaning of the abbreviation (if it is an > abbreviation). > Can I get this part by typing the command line? > > I'd appreciate it if someone could help me with that! > > BW！ > Wang > > > > > > > > -- > You received this message because you are subscribed to the Google Groups " > casper@lists.berkeley.edu" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to casper+unsubscr...@lists.berkeley.edu. > To view this discussion on the web visit > https://groups.google.com/a/lists.berkeley.edu/d/msgid/casper/966891fe-31ae-4280-a4e4-18a71f94a12cn%40lists.berkeley.edu > <https://groups.google.com/a/lists.berkeley.edu/d/msgid/casper/966891fe-31ae-4280-a4e4-18a71f94a12cn%40lists.berkeley.edu?utm_medium=email&utm_source=footer> > . > -- You received this message because you are subscribed to the Google Groups "casper@lists.berkeley.edu" group.
