Map

class Data_Reduction.GAVRT.Map(parent, raster_cfg_id, name=None)

Bases: Data_Reduction.GAVRT.Observation

Class for all the data and methods associated with a raster scan map

Public attributes:

cfg         - raster configuration
cfg_id      - entry in the raster configuration tableshape
channels    - list of channels which took tlog data
map_data    - dict of data from tlog table; 'tsrc' is dict keyed on channel
logger      - logging.Logger object
name        - map identifier
raster_data - data from the raster table
regrid      - computes map data onto a rectangular grid
rss_cfg     - receiver configuration
session     - observing session to which this map belongs
start       - UNIX time at start of map
end         - UNIX time at end of map

Public methods:

get_map_config      - returns a dict with the raster map configuration
get_raster_data     - gets the data for a raster scan map used for Zplot
get_raster_keys     - returns rasters associated with a given configuration

Methods Summary

get_map_config()	returns a dict with the raster map configuration
get_raster_data()	gets the data for a raster scan map extracted for Zplot
get_raster_keys()	Returns the rasters associated with a given configuration

Methods Documentation

get_map_config()

returns a dict with the raster map configuration

This is the map generated for display during the observing session. The observer selects a channel. Other channel data are recorded in the t-logs for the channels enabled.
