To arrange access to the physical plates, please contact the Cornell University Library Rare and Manuscripts Collection at rareref@cornell.edu Description: This document was produced by the Astronomy department at Cornell at some point between 1961 and 1965 to accompany the Palomar Sky Survey (POSS-1) glass plates. The materials were first housed in the Space Sciences Building and moved to the Physical Sciences Library. They now reside at the Rare and Manuscript Collections Division in Kroch Library. 2013-04-16T00:00:00Z http://hdl.handle.net/1813/3508 Title: IDL's datareduction v0.23 Authors: Rojo, Patricio Abstract: The routines in this package are intended to reduce spectral data as described in Patricio Rojo's Ph.D. dissertation (2007).

This method is particularly useful for flat fields in the common case where fringes vary between the calibration and object data. We analyze the efficacy of this method by creating fake flats with fictitious fringes and removing the fringes. We find that the method removes 90% of the fringe pattern if its amplitude is equal to the random noise level and 60% if the fringe amplitude is ~1/10 of the noise level. We also present examples using real flat-field frames. Version 1.5.5 of a routine written in IDL that implements this algorithm is available from the authors and as an attachment to this paper.

This is version 0.16 of the 'utils' package. The package provides routines to read and convolve data files, to make plotting windows user-interactive, and to resample arrays in different coordinates, among others. 2006-09-14T20:14:14Z
