This is an announcement of an updated version (1.8.1) of my quick-and- 
dirty, Python-based telescope archive search tool, available here:


(A short summary of what it does is appended below.)

Recent fixes:
- Restored coordinate lookup for object names via SIMBAD (broken due to 
changes in SIMBAD output HTML)

- Ancillary package fetchsdss now correctly retrieves all available imaging fields 
associated with a search, instead of just the first field

Changes/updates during the past year:
- Added the new, La Palma-based Isaac Newton Group archive, replacing the old 
ING archive server which didn't include new data (and wasn't really working anymore).
Also restored proper access for both CFHT and UKIRT (now using CADC searches
for both).

- Removed NOAO archive due to its switching to JavaScript (instead of HTML)

- SDSS DR12 searches also include optical spectra

[previous summary, updated:]

"Telarchive" is a command-line program which simplifies searching
various public telescope archives to see if they might have data on a
particular astronomical object or part of the sky.  This includes the
HST and general MAST archive (and Spitzer), as well as the ESO, UKIRT,
CFHT, ING, Gemini, SMOKA (Subaru), and AAT ground-based archives, and
both imaging and spectroscopic data from Data Releases 7 (DR7) and DR12
of the Sloan Digital Sky Survey.

The program won't *get* the data for you, of course (but see "fetchsdss"
for SDSS images and spectra), or even tell you very much about it -- for that, you
still need to visit the individual archive web pages.  But it will save you
lots of clicking and typing in web-page forms if you just want to find out
if there is *any* data available.

An example (searching within a 2-arcminute box centered on the planetary
nebula NGC 7027; searching on coordinates directly is also possible):

$ telarchive "ngc 7027" 2.0
	SIMBAD (Simbad 4, France): Found object coordinates: RA = 21 07 01.8, Dec = +42 14 10

Searching archives for ngc 7027 (RA = 21 07 01.8, dec = +42 14 10), with search box =  2.0 arcmin...
	AAT Archive: No data found.
	ESO Archive: Data exists! (2 observations found)
		2 spectra
	HST archive: Data exists! (109 records found)
		13 FOS, 3 FOC, 25 WFPC, 18 WFPC2, 26 NICMOS, 24 STIS
	Multimission Archive at STScI (MAST): Data exists! (37 observations found)
		COPERNICUS (1); FUSE (2); IUE (34)
	Spitzer archive: Data exists! (13 records found)
		1 mipssed, 2 iracmap, 3 mipsphot, 7 irsstare
	Sloan Digital Sky Survey (DR7+DR12): No data found.
	Gemini Science Archive: No data found.
	CFHT Archive: Data exists! (419 observations found)
		GECKO (4), GRIF (48), BEAR (361), aobir (6)
	UKIRT Archive: Data exists! (259 observations found)
		UFTI (51), Michelle (208)
	SMOKA (Subaru Mitaka Okayama Kiso Archive): No data found.
	ING Archive (La Palma): Data exists! (893 observations found)
		595 images, 298 spectra
		WHT -- ISIS (217), WHIRCAM (6), TAURUS (5), LIRIS (573), LDSS (4), UES (69); INT -- WFC (13), IDS (5); JKT -- JAG (1)

It's available as a gzipped tar file here:

There are installation instructions/suggestions in the README file.
(The code is currently Python-2 only, though I’m working on upgrading it for
Python 3.)

(And feel free to email with questions or suggestions about it!)
