1. Calibration of Linear Ramp Filter Data
... Calibration of Linear Ramp Filter Data . ... LRF Data . ... NOTE: LRF data retrieved from the WFPC2 static archive, implemented in the fall of 2009, has already been flat fielded. ... Currently, images observed with the linear ramp filters are not flat field calibrated in the calibration pipeline. ... We recommend using a narrow band filter flat at a wavelength near to the LRF observation wavelength (see list of narrow band flats below). ... If using LRF filter give desired Central Wavelength: . ...
