What is the process for extracting CHIME/FRB data files?

Illustration of a Rapid Radio Burst

I'm encountering an issue with msgpack.py while attempting to read and decompress msgpack data. The files I'm working on uncompressing are located here: CHIME/FRB data files. For further assistance, you can refer to this link: PyPi msgpack.

Has anyone dealt with reading CHIME/FRB data files before? If so, could you please guide me through the process?

 import msgpack
 from io import BytesIO

 buf = BytesIO()
 for i in range(100):
   buf.write(msgpack.packb(i, use_bin_type=True))

 buf.seek(0)

 unpacker = msgpack.Unpacker(buf, raw=False)
 for unpacked in unpacker:
    print(unpacked)

Answer №1

Unpacking the "astro" data may seem like a straightforward task, but it is not without challenges. One major obstacle is the sheer size of the data, which includes various undisclosed binary information.

To successfully unpack the file named "astro_10889573_20180814144950703901_beam1180_00161339_01.msgpack," follow these steps:

import pprint
import msgpack

data_msgpack = "astro_10889573_20180814144950703901_beam1180_00161339_01.msgpack"
with open(data_msgpack, mode="rb") as fd:
    data = msgpack.unpack(fd)

pprint.pprint(data)

The initial segment of the output appears as follows:

['assembled_chunk in msgpack format',
 1,
 0,
 16777216,
 1180,
 16,
 16,
 384,
 64,
 65536,
 16777216,
