Usability
Quick and easy to use?
- The software is designed to be general purpose, we have used it for
optical work on with the INT WFC, the JKT, the CTIO 0.9-m and for
infrared work with INGRID on the WHT.
- The catalogues we have published (and made available in electronic
form) amount to photometry of over 100,000 stars (though some stars
appear in more than 1 catalogue).
We are about to start work on data from the ESO 2.2-m + WFI.
-
If a particular instrument has been used before it typically takes an
experienced user
day to run a few pointings (of many CCD images) through the system
once the data are de-biased and flat-fielded.
-
But the system is NOT a pipeline.
Every instrument is different, and you need to explore it to find out
what the best reduction parameters are.
-
The images input into the system have to be translated from FITS to a
local format, but the system could be made to run on FITS images if
required.
The outputs are ASCII tables of field ID, star number, RA, Dec, pixel
X and Y, and then magnitudes and colours with errors and flags.
