# This section should be written with a GO audience in mind -- use 
# Calibration plans in WFPC-2 handbook as a guide.

Purpose: To obtain lamp spectra with the new G140L/1280 setting. These spectra will be incorporated in the lamp template reference file, which is used by the pipeline to calibrate data obtained with G140L/1280.

Description: This program obtains lamp template spectra with G140L/1280 at all
FPPOS, after a 1800 sec exposure that is used to let the OSM1 mechanism settle.
This 1800 sec exposure has flashes of the lamp at regular intervals so that any drift if present can be monitored. The data obtained in this program will be used to update the FUV lamp template reference file used by the calCOS pipeline.

Fraction of science programs supported by this calibration: For Cycle 18 this mode (G140L/1280) will replace the mode G140L/1230. 

List categories of science which can't be executed until after this proposal:
All science that uses the new G140L/1280 setting
why: Because no lamp template available for calibration.

List categories of science which are best performed contemporaneous with 
this proposal: N/A
why: N/A

# Exposure list plan at the Phase I level. Be as complete as reasonable.

# though, as this is a phase-1 issue.)
