Overview
This catalog contains metadata for NEOWISER Level 1b frames. Each row in the catalog consists of metadata for a single frame, and is uniquely identified by the scan_id, frame_num, and band columns. A complete listing of available columns can be accessed by clicking the link above.
Metadata queries can be issued at the following URL:
For example, <root>/search/wise/neowiser_yr5/yr5_p1bm_frm?POS=0,0 returns metadata for images containing (RA,Dec) = (0, 0). Query parameters are documented here.
Generating URLs for data products
NEOWISER Year 5 Level 1b data product URLs are built using the values of the scangrp, scan_id, frame_num, and band columns. Note that the last 2 characters of a scan_id yields the corresponding scangrp, so the latter column is not strictly necessary when building URLs.
Note: MD5 checksums for all data products are stored. Checksum URLs are obtained by simply appending ".md5" to the data product URL.
- Intensity FITS images

These are located at:
<server><root>/data/wise/neowiser_yr5/yr5_p1bm_frm/{scangrp:s}/{scan_id:s}/{frame_num:03d}/{scan_id:s}{frame_num:03d}-w{band:1d}-int-1b.fitsExamples:
- <root>/data/wise/neowiser_yr5/yr5_p1bm_frm/3b/89313b/121/89313b121-w1-int-1b.fits
- <root>/data/wise/neowiser_yr5/yr5_p1bm_frm/8b/89278b/041/89278b041-w1-int-1b.fits
By appending center and size parameters (e.g <root>/data/wise/neowiser_yr5/yr5_p1bm_frm/3b/89313b/121/89313b121-w1-int-1b.fits?center=195.79,7.9&size=200pix), one can also download cutouts (see the detailed documentation).
Python code to build a URL:
params = { 'scan_id': '89313b', 'frame_num': 121, 'band': 1, } params['scangrp'] = params['scan_id'][-2:] path = str.format( '{scangrp:s}/{scan_id:s}/{frame_num:03d}/{scan_id:s}{frame_num:03d}-w{band:1d}-int-1b.fits', **params) url = 'serverroot/data/wise/neowiser_yr5/yr5_p1bm_frm/' + path
C code to build a URL:
char url[256]; const char *scan_id = "89313b"; const char *server = "serverroot"; int frame_num = 121; int band = 1; snprintf(url, sizeof(url), "%s/data/wise/neowiser_yr5/yr5_p1bm_frm/%s/%s/%03d/%s%03d-w%1d-int-1b.fits", server, scan_id + (strlen(scan_id) - 2), scan_id, frame_num, scan_id, frame_num, band);
Java code to build a URL:
String scan_id = "89313b"; String server = "serverroot"; int frame_num = 121; int band = 1; String url = String.format("%1$s/data/wise/neowiser_yr5/yr5_p1bm_frm/%2$s/%3$s/%4$03d/%3$s%4$03d-w%5$1d-int-1b.fits", server, scan_id.substring(scan_id.length() - 2), scan_id, frame_num, band);

Append center and size parameters to these URLs to download a cutout instead of a full image (see the cutouts documentation).
A trivial change to the format string in the sample code snippets above suffices to generate these URLs.

- Positions of spurious sources from diffraction spikes
-
These are stored in IPAC ASCII table files containing 2 columns: ra and dec, the J2000 right ascensions and declinations of NEOWISER Level 1b sources believed to be spurious detections from diffraction spikes. If there are no such sources for a frame, then no position table is stored and visiting the URL generated according to the recipe below will return a 404 Not Found HTTP response. The tables are located at:
