Goal: We seek longslit spectra of E+A galaxies to assess their spectral properties

Observing Procedure/Exposure Times:

  1. Go to coordinates of the galaxy at any PA
  2. Expose

Necessary Calibrations: We will need arcs, biases, spectral flats with the same setups.

Conditions: This project can be done in poor seeing conditions, by increasing exposure times. However, pairs with small separation (<2-3") require good seeing conditions. Extinction is not desirable.

Exposure time:

For each source, we do 2x900s in the blue and 3x580s in the red.
