imap_processing.idex.idex_l1a.RawDustEvent#

class imap_processing.idex.idex_l1a.RawDustEvent(header_packet: SpacePacket)#

Encapsulate IDEX Raw Dust Event.

Encapsulates the work needed to convert a single dust event into a processed xarray dateset object.

Parameters:

header_packet (space_packet_parser.SpacePacket) – The FPGA metadata event header.

HIGH_SAMPLE_RATE#

The high sample rate in microseconds per sample.

Type:

float

LOW_SAMPLE_RATE#

The low sample rate in microseconds per sample.

Type:

float

NUMBER_SAMPLES_PER_LOW_SAMPLE_BLOCK#

The number of samples in a “block” of low sample data.

Type:

int

NUMBER_SAMPLES_PER_HIGH_SAMPLE_BLOCK#

The number of samples in a “block” of high sample data.

Type:

int

MAX_HIGH_BLOCKS#

The maximum number of “blocks” for high sample data.

Type:

int

MAX_LOW_BLOCKS#

The maximum number of “blocks” for low sample data.

Type:

int

_append_raw_data(scitype, bits)#

Append data to the appropriate bit string.

_set_sample_trigger_times(packet)#

Calculate the actual sample trigger time.

_parse_high_sample_waveform(waveform_raw)#

Will process the high sample waveform.

_parse_low_sample_waveform(waveform_raw)#

Will process the low sample waveform.

_calc_low_sample_resolution(num_samples)#

Calculate the resolution of the low samples.

_calc_high_sample_resolution(num_samples)#

Calculate the resolution of high samples.

_populate_bit_strings(packet)#

Parse IDEX data packets to populate bit strings.

process()#

Will process the raw data into a xarray.Dataset.

__init__(header_packet: SpacePacket) → None#

Initialize a raw dust event, with an FPGA Header Packet from IDEX.

The values we care about are:

self.impact_time - When the impact occurred. self.low_sample_trigger_time - When the low sample stuff actually triggered. self.high_sample_trigger_time - When the high sample stuff actually triggered.

Parameters:

header_packet (space_packet_parser.SpacePacket) – The FPGA metadata event header.

Methods

__init__(header_packet)

Initialize a raw dust event, with an FPGA Header Packet from IDEX.

process()

Will process the raw data into a xarray.Dataset.
