Object, Setup & Exposure Table Examples
Following are examples of tables required for the Texas share
Phase I, section 5, Description of Observations &
Justification of Exposure Times.
For the most up to date calibration and throughput information
see:
Please use the acceptable instrument setups in the Setup Table, as
they will also be used by you in providing your Phase II
documentation.
Fill out the Object Table. For large surveys, only enter enough
objects to show the range of observation parameters. The
"Acquisition ID Method" should be a short phrase such as:
Finder Chart
Accurate Coordinates
Distinctive Object
Blind Offset from bright star
Replace the sample entries with your own. Add lines to the table
as needed.

Setup Tables are not required for LRS2, VIRUS, or HPF.
The UT HET TAC requests that you plan for a 10 minute overhead on
each observation (even though the actual overhead time is often
shorter than that).

Note 1: HPF observation.
Note 2: LRS2-B observation
Note 3: LRS2-R observations, each observation should have its own
line in the table, but for large surveys a summary line like this
is fine, providing the individual exposure times are used in
calculating the total.
