Version 0.5

This version provides multiple improvements targeted at Juno/Waves and TRACERS support. It requires IDL version 8.5 or higher. Updates include:

• Building against a new das2C (58cd247, post 2.3.0), which provides all enhancements listed for the 2.3.0 release plus credential handling
• The ability to create, list, load and save server credentials for accessing protected data sources
• An API reference on the wiki
• The ability to enumerate data sources on a server
• Control over das2C logging verbosity
• Examples of fetching and plotting data for Juno/Waves and the upcoming TRACERS mission
• And various bug fixes, notably for multi-dataset query results.

The binary files below were built with IDL 8.9 and provide a mulit-platform DLM for Linux, Windows and MacOS. Unzipping the contents of the module file to some location on your IDL_DLM_PATH, then restarting IDL, is sufficient to install the module. Note that files go directly into your path, not in a sub-folder.

Feel free to open issues for any problems you encounter, and thanks for using Das2DLM.

Bug fix release for 0.4

This is a bug-fix release. No new features have been added.

Version 0.4.1 correctly handles queries that return no data (issue #9) and now routes das2C error messages resulting from invalid das2 streams to IDL so that they are visible to application code (issue #8).

The contents of both the zip file and the tarball are identical. Both include libraries for Linux (CentOS 7+, Ubuntu 14+), Windows 10, and MacOS (10.13+).

Client-side subsets

There are two major feature updates for this release:

• The das2c_data interface has been completed. Subsets of a variable may be read into user arrays. Previously the entire set of values needed to span the index space of a dataset were always returned from calls to das2c_data.
• Mac OS X, version 10.13 and up is now supported. The DLM contains a 64-bit MacOS binary.

The following planned version 1.0 features are not yet implemented:

• Data source discovery via the das2 catalog.
• Download progress display.
• Password protected data source access.

Since this is a pre-release, debugging symbols have been left in the binaries.
