I’m trying to download only the FUV level 1 IRIS data using the JSOC interface.

It’s pretty easy to generate a response that contains all the data (SJI, NUV, FUV) using the following code:

```auto
response = sunpy.net.Fido.search(
    sunpy.net.attrs.Time("2014-01-01T00:00", "2014-01-01T00:05"),
    sunpy.net.attrs.jsoc.Series("iris.lev1"),
    sunpy.net.attrs.jsoc.Notify("roytsmart@gmail.com")
)
response

```

Which outputs:

```auto
<sunpy.net.fido_factory.UnifiedResponse object at 0x0000016B0036D8D0>
Results from 1 Provider:

22 Results from the JSOCClient:

```

However, when I try to use the following code which I felt should work:

```auto
response = sunpy.net.Fido.search(
    sunpy.net.attrs.Time("2014-01-01T00:00", "2014-01-01T00:05"),
    sunpy.net.attrs.jsoc.Series("iris.lev1"),
    sunpy.net.attrs.jsoc.Notify("roytsmart@gmail.com"),
    sunpy.net.attrs.Instrument("FUV"),
)
response

```

I get an error

```auto

And when I used a slightly different code that was also suggested by the docs:

```auto
response = sunpy.net.Fido.search(
    sunpy.net.attrs.Time("2014-01-01T00:00", "2014-01-01T00:05"),
    sunpy.net.attrs.jsoc.Series("iris.lev1"),
    sunpy.net.attrs.jsoc.Notify("roytsmart@gmail.com"),
    # sunpy.net.attrs.Instrument("FUV"),
    sunpy.net.attrs.jsoc.Keyword("INSTRUME") == "FUV",
)
response

```

I get a different error that is hard to understand

```auto

Hi @byrdie,

So the first error comes from the fact that JSOCClient does not support the normal wavelength attribute. The error message unfortunately is pretty gibberish and needs to be improved in the future.

The second error I have the same issue and I am unsure if its a JSOC software issue or the query we send to the JSOC.

Can you see if you can filter on that keyword on the web UI? If so, I would imagine its a sunpy problem, but if not, we might need to reach out the jSOC.

Cheers,  
Nabil

HI Nabil,

Thanks for your response, I’m glad I’m not missing something obvious in the docs.

Just out of curiosity, do you know if there is any other way to acquire IRIS level 1 data? I was using JSOC since I am trying to port an IDL script, but I am willing to use anything that can get the job done.

> Can you see if you can filter on that keyword on the web UI? If so, I would imagine its a sunpy problem, but if not, we might need to reach out the jSOC.

It seems like filtering that keyword does work on the web UI, here is a screenshot of my attempt.

 ![jsoc](https://europe1.discourse-cdn.com/flex005/uploads/openastronomy/original/1X/2deddecdb1f76a5c992cf0f8ab8fc3902d6122bf.png)

I would be willing to open a PR to try and fix this if you don’t think it’ll be too difficult.

Thanks,  
Roy

Hi Roy,

In that case, I would at first glance assume the query we construct to the JSOC is incorrect. Finding what that query is and the difference to the website query hopefully will tell us what is broken.

In the meantime, I assume that you want a searchable interface and not just a directory of files? The SDAC has a mirror of level 1 files ([Index of /iris/iris\_data/level1](https://umbra.nascom.nasa.gov/iris/iris_data/level1/)) but it is not searchable by an API. You could scrape the server but its more work.

Thanks,  
Nabil

Hi Nabil,

> In that case, I would at first glance assume the query we construct to the JSOC is incorrect. Finding what that query is and the difference to the website query hopefully will tell us what is broken.

I lazily stuck a print statement into `drms.client.Client.query()` and I found that the generated query was

```auto
ds='iris.lev1[2014.01.01_00:00:35_TAI-2014.01.01_00:05:35_TAI][? INSTRUME=FUV ?]'

```

which incorrectly doesn’t have quotes around the `FUV`.

So, a temporary workaround is just to manually insert the quotes

```auto
response = sunpy.net.Fido.search(
    sunpy.net.attrs.Time("2014-01-01T00:00", "2014-01-01T00:05"),
    sunpy.net.attrs.jsoc.Series("iris.lev1"),
    sunpy.net.attrs.jsoc.Notify("roytsmart@gmail.com"),
    sunpy.net.attrs.jsoc.Keyword("INSTRUME") == "'FUV'",
)
response

```

which outputs

```auto
<sunpy.net.fido_factory.UnifiedResponse object at 0x000002B250727610>
Results from 1 Provider:

6 Results from the JSOCClient:
Source: http://jsoc.stanford.edu

TELESCOP INSTRUME
-------- --------
    IRIS FUV
    IRIS FUV
    IRIS FUV
    IRIS FUV
    IRIS FUV
    IRIS FUV

```

I’m not sure if this is a bug in drms or Sunpy, but maybe it wouldn’t be too hard to open a PR to fix this.

Thanks for helping me to figure out the problem!

That will need to be fixed in sunpy. I can work on that and get that patched this week.
