Session

class Data_Reduction.GAVRT.Session(parent, year, doy)

Bases: Data_Reduction.Session

Class for an observing session on a given year and DOY

Public Attributes:

boresights    - dict keyed on 'xpwr_cfg_id' with 2D arrays for scan metadata
bs_channels   - dict keyed on 'xpwr_cfg_id' with lists of active channels
bs_data       - dict keyed on 'xpwr_cfg_id' with 2D rrays for 'tlog' data
db            - database
doy           - day of year for session
logger        - logging.Logger object
maps          - maps in this session
session_dir   - path to results from this session
xpwr_metadata - 2D array with data for each 'xpwr' configuration
year          - year for session

Notes on Data Arrays:

* 'boresights' 2D-arrays have a row for each scan of the boresight and
  columns for::
    0 - 'xscan_id',
    1 - 'xpwr_cfg_id', and
    2 - 'epoch'.
* 'bs_data' 2D-arrays have a row for each 'tlog' row and columns for::
    0 - UNIX time,
    1 - counts,
    2 - integration time,
    3 - azimuth,
    4 - elevation,
    5 - noise diode state, and
    6 - channel [if argument chan=None; see get_boresight_data()]
* 'xpwr_metadata' is a 2D-array with a row for each configuration and columns::
    0 - 'xpwr_cfg_id'
    1 - UNIX time,
    2 - rss_cfg_id,
    3 - source_id,
    4 - axis, and
    5 - chan

Methods Summary

get_map_IDs()
get_maps([map_IDs])	Returns maps from the raster configuration IDs for the specified date
get_session_dir()
list_maps([save])
make_bs_dir([good_only, save])	Notes
save_map_data([mapkeys])	create a dict with the map data from the designated images
summary([save])

Methods Documentation

get_boresights()

Returns boresights from the xpwr configurations

get_good_boresights()

Retrieves data from ‘tlog’ table for boresights with a given channel

Returns a numpy array with columns containing::

0 - UNIX time 1 - counts 2 - integration time 3 - azimuth 4 - elevation 5 - noise diode state 6 - chan (if chan=None)

get_map_IDs()

get_maps(map_IDs=[])

Returns maps from the raster configuration IDs for the specified date

get_session_dir()

list_maps(save=False)

make_bs_dir(good_only=False, save=False)

Notes

Each good boresight consists of two scans

save_map_data(mapkeys=None)

create a dict with the map data from the designated images

This speeds up retrieval of images

:param mapkeys : numbers of the maps (default: all) :type mapkeys : list of int
