Overview
Processed data corresponding to the original single CCD exposures. These individual image files are sometimes simply referred to as "single exposure", "processed images", or even sometimes "frameproc." Level-1 data can consist of calibrated FITS images, mask images, and calibrated photometric catalogs in binary FITS table format. At this time, all publicly available data are Level 1 data, but not all Level 1 data are publicly available. If you have proprietary access to these data, you must log in to be able to download these data. 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/ptf/images/level1?POS=0,0 returns metadata for images containing (RA,Dec) = (0, 0). Query parameters are documented here.
Generating URLs for data products
- Intensity FITS images
-
These are located at:
<server><root>/data/ptf/images/level1/{pfilename:s}where pfilename is the values of the column pfilename.
Examples:
By appending pfilename and size parameters one can also download cutouts (see the detailed documentation).
- Mask FITS images
-
These are located at:
<server><root>/data/ptf/images/level1/{afilename1:s}where afilename1 is the values of the column afilename1.
Examples:
By appending afilename1 and size parameters one can also download cutouts (see the detailed documentation).
- <root>proc/2012/09/20/f1/c0/p5/v1/PTF_201209202356_i_p_mask_t053919_u014094242_f01_p022592_c00.fits?center=0,0&size=200pix
Append center and size parameters to these URLs to download a cutout instead of a full image (see the cutouts documentation).
- SExtractor Catalog
-
These are located at:
<server><root>/data/ptf/images/level1/{afilename3:s}where afilename3 is the values of the column afilename3.
Examples:
