A list of FITS header keywords that need to be updated -- from RM:

For the rewrite, can you you please use v3.4 attached.

Main header:

NRCVR = 2
OBSBW = 32.0
OBSNCHAN = 256
COORD_MD = “J2000”

History table

SCALE = “UNCAL”
POL_TYPE = “AA+BB”
NSUB = the number of rows in the (completed) table.
NPOL = 1
CHAN_BW = 0.125

Subint table:

SCALE = “UNCAL”
POL_TYPE = “AA+BB”
NBIN_PRD = 1
NSUBOFFS = 0
NCHAN = 256 (replaces NCH_FILE)
CHAN_BW = -0.125
NCHNOFFS = 0 (replaces NCH_STRT)
NSBLK It might be good to increase this by a factor of 8 or maybe 16 to reduce the overhead of the subint header. At present the headers are about 10% of the data volume. A possible reason for not doing this is that you would generally have to pad the final row. Ideally this would be done with ones and zeros in alternate frequency channels for all pad samples.
DAT_FREQ. These should increase from 420.0625 as discussed above.

The symlink function outputs a warning if the file/link already exists.

We should either supress configure the web server to supress php warnings if we don't care if the symlinks already exist (ie are they always going to be correct?), or if we do care, we should check to see if the file exists before calling symlink

If you put a cal file in your cart and select "Download cal files only", it will load a page pointing to the downloads directory.

Also, if this option were selected, and no cal files were present in the cart, we would expect the same result.

This results from tarCalFiles returning an empty string. The code that calls it from query.php doesn't check the return value of tarCalFiles or output an error message if its empty.

so this ticket has 2 bugs

• no error output if tarCalFiles returns empty
• tarCalFiles returns empty even when there are cal files in the cart.
