Generating URLs for data products
2MASS Long Exposure (6X) Full Survey Atlas Image data product URLs are built using the values of the ordate, hemisphere, scanno, and fname columns.
- Long Exposure (6X) Full Survey FITS Images

These are located at:
<server><root>/data/twomass/sixxfull/sixxfull/{ordate:6d}{hemisphere:1s}/s{scanno:03d}/image/{fname:20s}Examples:
- <root>/data/twomass/sixxfull/sixxfull/991106s/s042/image/ji0420221.fits.gz
- <root>/data/twomass/sixxfull/sixxfull/000505n/s028/image/hi0280266.fits.gz
By appending center and size parameters (e.g. <root>/data/twomass/sixxfull/sixxfull/000505n/s028/image/hi0280266.fits.gz?center=160,54&size=100pix), one can also download cutouts (see the detailed documentation).
Python code to build a URL:
params = { 'ordate': 991106, 'hemisphere': 's' 'scanno': 042 'fname': 'ji0420221.fits.gz' } path = str.format( '{ordate:6d}{hemisphere:1s}/s{scanno:03d}/image/{fname:20s}' **params) url = 'serverroot/data/twomass/sixxfull/sixxfull/' + path
C code to build a URL:
char url[256]; const char *ordate = "991106"; const char *hemisphere = "s"; const char *fname = "ji0420221.fits.gz"; const char *server = "serverroot"; int scanno = 42; snprintf( url, sizeof(url), "%s/data/twomass/sixxfull/sixxfull/%s%s/s%03d/%s", server, ordate, hemisphere, scanno, fname );
Java code to build a URL:
String ordate = "991106"; String hemisphere = "s"; String fname = "ji0420221.fits.gz"; String server = "serverroot"; int scanno = 42; String url = String.format( "%1$s/data/twomass/sixxfull/sixxfull/%2$s%3$s/s%4$03d/%5$s", server, ordate, hemisphere, scanno, fname );

- <root>/data/twomass/sixxfull/sixxfull/991106s/s042/glint.tbl
- <root>/data/twomass/sixxfull/sixxfull/000505n/s028/glint.tbl
A trivial change to the format string in the sample code snippets above suffices to generate these URLs.
