daschlab Package¶

The toplevel Python module of the daschlab package.

daschlab is a Python package that assists with astrophysical analysis of data from DASCH, the effort to scan Harvard College Observatory’s collection of astronomical glass plates. This irreplaceable resource provides a means for systematic study of the sky on 100-year time scales.

This website contains only the Python API reference material. For tutorials and howtos, see the DASCH DR7 documentation.

This package is designed for primarily interactive usage in a JupyterLab environment. The most important item provided in this module is the Session class, which defines a daschlab analysis session. Obtain a session by calling the open_session() function:

from daschlab import open_session

sess = open_session(".")

Virtually all subsequent analysis occurs through actions connected to an initialized Session instance.

Functions¶

`get_concept_doi`()	Get the "concept DOI" that identifies the daschlab software.
`get_version_doi`()	Get the DOI associated with the exact version of daschlab that you are running.
`open_session`([root, source, interactive, ...])	Open or create a new daschlab analysis session.
`source_name_to_fs_name`(name)	Convert the name of an astronomical source to something convenient to use in file names.

Classes¶

`InteractiveError`	A error class for errors that should be shown to a human user without traceback context.
`Session`(root[, interactive, _internal_simg])	A daschlab analysis session.
