This directory contains DKIST/DL-NIRSP level 1 data from PID_3_90
observed on 14 April 2025.  It was processed by S. Jaeggli on the NSO
Maui compute nodes using the preliminary DL-NIRSP pipeline v0.21.0
(2025-02-06).

Within this directory there are 6 datasets corresponding to 3
observing programs.  Each observing program includes data from
DL-NIRSP Arm 1, with the Ca II 854 nm channel, and Arm 3, with the Fe
I 1565 nm channel.

This is a preliminary leve 1 data product and there are known issues
with its calibration.  The wavelength has been linearized, but the
wavelength offset and dispersion are not accurate.  There are still
artifacts related to the integral field spectra flat field.  Please
contact S. Jaeggli (sjaeggli at nso dot edu) with any questions or
concerns.

Examples of how to interact with the DL-NIRSP level 1 data products
can be found on GitHub at

This release is preliminary and provided to accompany other publicly
released datasets collected on 14 April 2025.  Upon release of the
first version of the DL-NIRSP processing pipeline at the DKIST Data
Center, this dataset should be removed and replaced with the most
recent Data Center product.
