Ganeshalingam13
[source]¶ The
Ganeshalingam13
class provides access to BVRI light curves of 165 objects published by the first data release of the Lick Observatory Supernova Search (LOSS) conducted between 1998 and 2008. (Source: Ganeshalingam et al. 2013)- Deviations from the standard UI:
- None
- Cuts on returned data:
- None
-
delete_module_data
() → None¶ Delete any data for the current survey / data release
-
download_module_data
(force: bool = False, timeout: float = 15)¶ Download data for the current survey / data release
Parameters: - force – Re-Download locally available data
- timeout – Seconds before timeout for individual files/archives
-
get_available_ids
() → List[str]¶ Return a list of target object IDs for the current survey
Returns: A list of object IDs as strings
-
get_available_tables
() → List[Union[str, int]]¶ Get Ids for available vizier tables published by this data release
-
get_data_for_id
(obj_id: str, format_table: bool = True) → astropy.table.table.Table¶ Returns data for a given object ID
See
get_available_ids()
for a list of available ID values.Parameters: - obj_id – The ID of the desired object
- format_table – Format data into the
sndata
standard format
Returns: An astropy table of data for the given ID
-
classmethod
get_zp_for_band
(band: str) → str¶ Get the zeropoint for a given band name
Parameters: band – The name of the bandpass
-
iter_data
(verbose: bool = False, format_table: bool = True, filter_func: bool = None) → astropy.table.table.Table¶ Iterate through all available targets and yield data tables
An optional progress bar can be formatted by passing a dictionary of
tqdm
arguments. Outputs can be optionally filtered by passing a functionfilter_func
that accepts a data table and returns a boolean.Parameters: - verbose – Optionally display progress bar while iterating
- format_table – Format data for
SNCosmo
(Default: True) - filter_func – An optional function to filter outputs by
Yields: Astropy tables
-
load_table
(table_id: Union[int, str]) → astropy.table.table.Table¶ Return a Vizier table published by this data release
Parameters: table_id – The published table number or table name
-
register_filters
(force: bool = False)¶ Register filters for this survey / data release with SNCosmo
Parameters: force – Re-register a band if already registered
