Instrument Science Report NICMOS-018

NICMOS Paper Products: build 1
Luis Colina and Bill Sparks February 5, 1997

ABSTRACT. This report details the features of the NICMOS paper products produced by the HST data pipeline. The requirements closely follow the design of paper products recommended by the Data Quality Committee, although some changes were required to fully support NICMOS. Here we provide detailed design of build 1, with a subsequent build 2 anticipated.

1. Introduction
A routine part of the HST data is the post-calibration production of hardcopy products, or `paper products', that summarize the data obtained. The general problem of producing these products was studied extensively by the Data Quality Committee and is described in their report (Sparks, et al. 1995). These products are used for both informing the GO and for data quality evaluation by the contact scientists. As such, the products must be general enough to support both sets of users. This report describes in detail the requirements for the paper products that summarize NICMOS data.

2. Description of NICMOS Paper Products
NICMOS paper products are designed to summarize a set of exposures. Typically, the set of exposures will constitute one visit in an observing proposal. The individual pages in the paper product either describe the details of a single exposure that can be an association in the most general case. A given page in the NICMOS paper products falls into one of two categories: visit-level page or exposure-level page. Below we list the individual pages, the pages are described in detail in Section 3, "Page Generation and Layouts".

Visit-level Pages · Cover Page A cover page containing the proposal ID, the visit number, the PI's name, and the proposal title. · · · Explanatory Notes A set of notes explaining the paper products and the information they contain. Target List A table listing the targets in the set of observations being summarized. Observation Summary A table recapping the proposal information for each exposure for the set of observations being summarized including three processing and data quality flags. · Optional Parameters A table listing the optional parameters, other than pattern related parameters, for the set of observations being summarized. · Observing Pattern Strategy A table listing the observing pattern for each exposure for the set of observations being summarized. Exposure-level Pages · Exposure Plots A graphical representation of the data contained in each exposure including the final calibrated science image and, in case of associations, successive pages contain a cartoon of the observing pattern plus the on-target and background individual images. · Data Quality Summary A comprehensive summary of the spacecraft performance, pipeline processing status, and calibration data quality for each exposure. · Calibration Reference File Summary A summary of the calibration processing switches and reference files used to process each exposure.

3. Page Generation and Layouts
Table 1 summarizes the criteria for producing NICMOS paper products pages. The table lists the individual page types followed by the criteria that trigger the creation of a given page. For those pages that are always produced, the criterion is stated as "All". Additionally, the table lists the data files from which to extract the keyword and plot information. If no file can be found satisfying the selection criteria, a warning message is produced by the paper products task. Title Page The Title Page consists of a Header, and four (4) keyword/value pairs. See Table 2 for a description of the keyword-value pairs to be included on the Title Page. The visit and title keywords are found in the _spt file. The proposal and PI name keywords are found in the primary header of the _raw file. The keyword/value pairs are written in 20 point size. See page 17 for an example of the title page.

Explanatory Notes The Explanatory Notes page is an instruction sheet for using and understanding the collection of NICMOS paper products pages. As this information describes the paper products themselves, as opposed to the observations, this page does not change from visit to visit. The section headers are written in bold font style. The headers in each section are written in 12 point Narrow Helvetica Bold. The text in each section is written in 12 point Times. See Page 18 for an example of the explanatory notes. Target List The Target List is a table containing target names, positions, and target
