Abstract This proposal defines the spectral cal lamp mini-functional test for the first order gratings. It is an internal test which makes measurements of the lamp (SC2). It is used to calibrate the carrousel function, Y deflections, resolving power, sensitivity, and scattered light. It will be run frequently during SV. The carrousel and Y deflection function coefficients are determined and the PDB will be updated. The wavelength calibration dispersion constants will be updated in the PODPS calibration data base. ------------------------------------------------------------------------------------ 8.

GENERAL FORM Proposal 2767c PI: Dennis Ebbets Proposal Title: GHRS SV 1ST ORDER GRATING SPECTRAL LAMP TEST ------------------------------------------------------------------------------------ 1.

Scientific Justification. GHRS SV Objectives: Obtain routine calibration data for: 1. Carrousel calibration function coefficients. 2. Wavelength calibration dispersion constants. 3. Y deflection function coefficients. 4. Spectral resolving power, instrument profile. 5. Scattered light. 6. Grating to grating relative sensitivity. ------------------------------------------------------------------------------------ 3. Description of proposed observations. Observations will be made for the following first order gratings: Grating G1 (G140M), at 6 carrousel positions, for central wavelengths 1165, 1255, 1330, 1405, 1525, and 1705 Angstroms. Grating G2 (G160M), at 6 carrousel positions, for central wavelengths 1240, 1400, 1520, 1640, 1780, and 1940 Angstroms. Grating G3 (G200M), at 6 carrousel positions, for central wavelengths 1780, 1940, 2100, 2240, 2380, and 2500 Angstroms. Grating G4 (G270M), at 6 carrousel positions, for central wavelengths 2375, 2500, 2700, 2900, 3050, and 3200 Angstroms. Grating G5 (G140L), at 4 carrousel positions, for central wavelengths 1200, 1400, 1600, 1800 Angstroms. At each position, one spectral lamp (sc2) will be observed . Each observation will use substep pattern 3, with 4 samples per diode. The 2 point comb addition feature will be used, and a new spectrum Y balance offset will be calculated for each observation. ------------------------------------------------------------------------------------ 5. Description of special scheduling requirements. First execution should be early in SV. Repeats approximately every 6 weeks. Different gratings are independent tests, and need not be run together, or in any particular order. Prerequisites: 1. A HRS Standard High Voltage Turn On must have successfully been completed. 2. The OV spectral lamp mini-functionals, props 1363 -1367 must have been successfully run and analyzed. SV Minimum Plan: All SV Delta Plan: None Guiding Tolerance: None - internal test only ------------------------------------------------------------------------------------ 7. Data reduction and analysis plans. 1. Coefficients for the carrousel function and Y deflection function are determined and entered into the project database. These coefficients will be used to construct OSTs for subsequent observations using this grating. 2. Wavelength calibration dispersion constants are entered into the PODPS calibration database. 3. Other parameters are derived for performance monitoring. ------------------------------------------------------------------------------------ 8. Additional comments or special requests. This is an internal test and does not require any special pointing of the telescope. This test does not require the GHRS to be the prime science instrument. There is no target list with this proposal. ------------------------------------------------------------------------------------ 10. Resources to be supplied by investigator's institution(s). 1. Test design support. 2. Test execution support team. 3. Data analysis facilities. 4. Data analysis personnel.
