parse_cm.get_acis_tables

parse_cm.get_acis_tables(cfg_file=None, dat_file=None)

Parse the ACIS tables (.cfg and .dat files) and retrieve information.

From the configuration (.cfg) file: dictionary of SIMODES which contains the number of ACIS command packets, the specific packets used, and the delay times in seconds after each command.

From the data (.dat) file: dictionary of ACIS command packets with word_length, command_opcode, slot_id, file_format, packet_duration, and binary_data.

Looks first for an environment variable $ACIS_TABLES_DIR for the location of the tables, and failing that, looks in $SKA/data/acis_tables.

Parameters:

cfg_filestring or Path object, optional

The ACIS tables CFG file to use. Default is “current.cfg.”

dat_filestring or Path object, optional

The ACIS tables CFG file to use. Default is “current.dat.”

Returns:

Two Python dictionaries containing the .cfg and .dat

table information, in that order.
