Here are some examples of task names that I'd like to be able to understand:
13dc18aa.5576.7020.16.43.88.vlar_0
blc14_2bit_guppi_58405_78644_PSR_J2022+5154_0007.9620.409.22.45.66.vlar

I've noticed that the "13dc" tasks take longer than the "blc14" tasks. I remember reading once how you can read info about a task based on its name. Can anyone point me to the web page that explains this, or give me a quick review?

Things like: vlar, guppi, blc14, 13dc

Thanks in advance!

There are currently two telescopes providing data, and which one provided the data for a given task is in the first part of the file name.
If the first two cahacters are digits then the source was Arecibo, and the first 6 charactersss give the date of collection. Thhe next two characters give the reciever chanel, then comes a pile of characters giving information about sky location, time of day etc.
Those starting with "blc" are from thhe Green Bank telescope. The section starting with a group of letters indicates whic star catalogue and entry was being observed. The other biiiits of data escape me just now.
If the last bit of the nane is "vlar" the collected data only covers a very low sweep angle which is typical when 'staring' at one star rather than taking a wider view.
Finaly there are tasks statting with "ap" these are AstroPulse tasks, currently only from Arecibo data, their names are differnt, again I can't recall all the structure.

It would, but when the project started there was only one data source.

VHAR are the Very High Angle Range, these days a very rare task as the search is focused on stars known to have planets.

Cheers.

My SETI@home screensavers display the data origin and when they were collected. GreenBank data come out with a BreakthroughListen label.

Thanks everyone! That helps a lot. I use the lunatics version of the seti apps, so I can't see the screensaver to find out the info on the task anymore. I remember being able to do that in the past, and I read the web page on how to understand what it was telling us, so it made sense after a while. Originally, when I first downloaded BOINC back in July, the SETI screensaver was overwhelming.

Let's explain 05dc18aa:
"05 dc 18" represents 5 December 2018. (ja=January, fe=Februrary, mr=March, ap=April, my=May, jn=June, jl=July, au=August, se=September, oc=October, no=November, dc=December)
"aa" probably refers to Arecibo beam. (ab= Beam 3, aa=Beam 4)

I believe vlar is very low angle range.

Which means that when the signals for that WU were recorded at the Arecibo radio telescope, it was not moving very much and was 'staring' at a small section of the universe.
By the same token, VHAR stands for 'very high angle range', and means that the telescope was scanning much more quickly during the recording period.

The link below explains the name from a thread I post long ago.
