LMI Filter Characterization

LMI filter characterization with dome flats using fixed exposure times.

Details for each filter are given on the LMI Filter Information page.

For .fits links, rename both the link and attachment as lmi.UTDate.Filter.#.fits.

Example: lmi.0011.fits in the U filter from 20191107 will be renamed lmi.20191107.U.0011.fits

To do this, click the '...' symbol→ click 'attachments' page→click 'properties'. In Properties, you can rename a file. Once renamed, confluence will automatically label the link as it's file name on this page when attached.
