Subject: [AstroPy] A Mystery: DAOStarFinder Not Finding an Obvious Star
 in Just One Image
Message-ID: <CAP6WE=3eHGX3yKE0POW_3mzYuo2RvirLP3baLi_jyaazYGPdPQ@mail.gmail.com>

Thank you again, Eric, for your suggestions.

I do not believe that this star was not saturated.  I checked a number of
other stars in the image of equivalent or greater peak and total flux.
Interestingly, these experienced no issues.

Vizier indicates that the object in question, J102343.30+003819., is a star
rather than some extended object.  It registered without issue in other
exposures taken in conditions with significantly worse seeing.  My only
thought is perhaps some very localized seeing condition?

Anyway, I have relaxed my constraints on sharpness and found that this
captured the missing object without sweeping up "undesirables."  Problem
solved!

Thanks again!

Hi,

I am currently working with MGEFIT. There are some values connected to certain variables that I am unsure of what means, and I was wondering if anyone had any experience with MGEFIT who could help me interpret?

Hi everyone

A whole bunch of my codes have suddenly started failing, on 
astropy.time.light_travel_time

After much debugging I've found the issue: the code downloads a URL: 
ftp://anonymous:mail%40astropy.org at gdc.cddis.eosdis.nasa.gov/pub/products/iers/finals2000A.all 
and presumably expects to find leap seconds or something. Instead it 
gets HTML saying "This site is currently unavailable".

Ultimately, I get the error:

ValueError: Column year failed to convert: invalid literal for int() 
with base 10: '<!'

Obviously from the <!DOCTYPE in the HTML page.

This is causing me major headaches, as I have some pretty critical 
scripts affected. Is there an easy solution, eg. for me to blacklist the 
above URL or something?

Thanks

Phil

Hi Phil,

I had a similar error but running something different,

I uninstalled Astropy and reinstalled it using: pip3 install astropy[all],
I am running it on ubuntu 20.04.4 LTS...

And Finally, it worked.

Hi Ramiro and others,

I tried reinstalling astropy but no luck. For now, I?ve got a semi-fix because it was working on another machine (which had obviously downloaded from a different site) so I copied my .astropy directory across, but this is ony short-term, and doesn?t deal with the underlying problem that astropy is downloading essentially a 404 page and so throwing an error - that there doesn?t seem to be a way to avoid.

Is there no way to set preferences or blacklist a given URL? I don?t know the intimate details of astropy, but it downloads sites.json, so I assume from this it selects where to get the IERS stuff from(?) So ideally I?d like to be able to say, ?Don?t use that site.? Actually - more ideally, the back-end of astropy should realise when the file it has downloaded is not the expected file and switch to a different source ? I guess maybe I should report this as a bug on the git repo?

Phil

Hi Phil, 

You should be able to edit your .astropy/config/astropy.cfg file and find the iers section there to set some things, for example to set auto_download to False.   Details on the iers config parameters are here:  https://docs.astropy.org/en/stable/utils/iers.html#configuration-parameters <https://docs.astropy.org/en/stable/utils/iers.html#configuration-parameters> 

It looks like you can also edit the iers_auto_url parameter to point to a different URL if you like. 

I agree that ideally astropy should recognize if it?s not getting sensible output from a given download, so that could be a good issue to open.  But perhaps the above will help in the short term. 

Hope this helps -

It's a long time I did not work w/ MGEFIT (2004A&A...415..889C!), the current "reference" python
implementation is Michele Cappellari's one at
https://www-astro.physics.ox.ac.uk/~cappellari/software/#mge

Is this the one you're using?

Just rounding this off a bit more:

If I download the file myself: (curl -u anonymous: -O --ftp-ssl 
ftp://gdc.cddis.eosdis.nasa.gov/pub/products/iers/finals2000A.all) the 
file downloads fine, but when astropy does it (saying "Downloading 
ftp://anonymous:mail%40astropy.org at gdc.cddis.eosdis.nasa.gov/pub/products/iers/finals2000A.all 
from https://datacenter.iers.org/data/9/finals2000A.all") it gets the 
"service not available" error).

I will report to astropy git as an issue - has anyone else seen this? 
Easy steps to reproduce (first moving your .astropy directory away so 
that you don't keep a cached file)

mv ~/.astropy ~/.astropy_KEEP
ipython3

from astropy.time import Time
Time.now().ut1


And I get an error.

THanks


Phil
