ACS Flat Field Update and New SBC L-flats
نویسندگان
چکیده
We present an overview of the methods used to create the flat fields which are currently in use by the ACS calibration pipeline. L-flats for the SBC detector have recently been computed using dithered star cluster observations. Large corrections to the existing flats are required at the 10-20 percent level, depending on wavelength. A comparison with sky flats obtained via observations of the bright Earth indicate that the current pipeline flats are accurate at the 1-2 percent level.

Flats: Sbc Data from Thermal Vacuum Testing
The Advanced Camera for Surveys (ACS) has three detectors: a large and a small format CCD (WFC and HRC), and a 1024x1024 MAMA Solar Blind Channel (SBC). During the Thermal Vacuum testing at GSFC in 1999 March, flats with S/N=100 per pixel were obtained for the six SBC filters and two prisms. The pixel-to-pixel P-flats are independent of wavelength to <1%. Because of a temperature dependence in ...
متن کاملDetermination of Low-Frequency Flat-Field Structure from Photometry of Stellar Fields
The low-frequency content of ACS flat fields cannot be accurately determined from ground-based calibration data or internal lamp exposures. It must therefore be determined from on-orbit science data. Photometry of a stellar field that is imaged multiple times with different pointing or roll is ideal for this purpose. I describe a mathematical algorithm to use such data to determine the residual...
متن کاملWFC L - Flats Post Cooldown
Following recovery of ACS with Side 2 electronics the temperature setpoint was lowered from a nominal value of-77 C to-81 C for the WFC in order to minimize impacts of the continuously growing hot pixel contamination. The CCDs are expected to have changes of 1-3% in overall sensitivity, with some spatial dependence (Sirianni et al. 2006) – the latter is calibrated via changes to the L-flats. We...
متن کاملSTIS CCD spectroscopic P-flats
The analysis of the cycle 17 STIS CCD spectroscopic flats (Niemi 2010) pointed to the need to create a new dust mote image for the low resolution grating (L-mode) P-flats. This ISR describes the creation of the new L-mode P-flat from low resolution exposures taken during cycles 18 and 19. The document also analyzes the time dependence of the dust mote images as well as that of the intrinsic fla...
متن کاملACS L - Flats for the WFC
The uniformity of the WFC detector response has been assessed by using multiple dithered pointings of moderately dense stellar fields. By placing the same star over different portions of the detector and measuring relative changes in brightness, local variations in the response of the detector have been measured. The original WFC laboratory flat fields produce photometric errors of to percent f...
