class
sndata.sweetspot.
DR1
[source]¶ SweetSpot is a 3 yr National Optical Astronomy Observatory (NOAO) survey program to observe Type Ia supernovae (SNe Ia) in the smooth Hubble flow. DR1 includes data from the first half of this survey, including SNe Ia observed in the rest-frame near-infrared (NIR) in the range 0.02 < z < 0.09. Because many observed supernovae require host-galaxy subtraction from templates taken in later semesters, this release contains only the 186 NIR (JHK s ) data points for the 33 SNe Ia that do not require host-galaxy subtraction.

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

-
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

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

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
