Introduction
The GBPP (Green Bank - Berkeley pulsar processor) is a
machine for measuring pulsar timing which employs
digital de-dispersion implemented in hardware.

How to get started in Green Bank
- ssh osiris -l dbacke r
- cd /gbpp0/mpulsar/gbpp/onlingb t
- DOGBPP2 {this starts up a GUI}
- go into the locked room where the GBPP PC is located.
- type "CNTRL-C", then "Yes", to stop the 85-3 program.
- reboot the GBPP PC by pushing the "reset" button.
- give Don's password when asked.
- type: cd 97feb\data
- type: gogbt1
- everything else is done from the session on osiris that was
started up in steps 1 and 2.
- the astronomer needs to produce a "polyco.dat" file.
Copy this file into the directory "/gbpp0/mpulsar/gbpp/onlingbt/"
- "dossify" the polyco.dat file:
unix2dos polyco.dat polyco.dos
- In the DOGBPP2 GUI, select the correct rfif table,
for example if observing at 1400 MHz, choose "rfif1400.tbl",
then press the "UpdAll" button.
- Now it should be ready for observing.
- (To go back to the 85-3 program, repeat steps 4-8, but
then type "go" instead of "gogbt1")

- Don's instructions

File paths
- GBT data: /home/gbpp0/mpulsar/gbpp/datagbt
- 853 data: /home/gbpp1/mpulsar/gbpp/data85
