Visiting the URL ​http://pulsararchive.atnf.csiro.au/ takes you to a login page.

This page should be reworked so that it allows anonymous access to the search form, but also allow people who want to check for data still in the proprietary period to authenticate themselves.

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.

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.
