With Python 3.5.2 and matplotlib version 2.2.2, I get an error saying that there is no ax.set_axis_bgcolor function. Apparently this has been deprecated since matplotlib 2.0 (https://matplotlib.org/2.1.2/api/_as_gen/matplotlib.axes.Axes.set_axis_bgcolor.html). As a result, all instances of "set_axis_bgcolor" should be changed to "set_facecolor" throughout the script plot.py
I just tried to install SPIDERMAN from the GitHub version, but get the following error. Is this a python version issue?

I am fitting a Spitzer phase curve with the SPIDERMAN model, but at every iteration of the LMFIT, the routine outputs this:
no stellar models provided, using blackbody approximation
How do I supply it with a stellar model? Or, how do I suppress this warning?
Thank you
Using LMFIT to fit sine waves to Spitzer data, I can usually fit the model to 60k data points in ~15 seconds with leastsq
as the method, and ~200 seconds with powell
as the method.
With SPIDERMAN, using leastsq
, it takes 650 seconds. I am still processing it with powell
, but the point is that it's not even close to done yet.
Do you have any suggestions to speed up the fitting process? Do we have to create a new Parameters every single time (I tried not doing that). Is there a 'fast' version with less options?
Thank you
I would be very grateful if you could help me fix this error.
Thank You

Hi Tom, Laura,
I noticed that the condition to calculate temperature for the Zhang & Showman model in the brigthness_maps.c file does not seem to account for negative xi values. This relates to line 224 and the condition :
if(xi < 0.01)
Their model allows for hotspot offsets eastward as well as wesward, so xi can be negative. I think that replacing the condition by
if(fabs(xi) < 0.01)
should do the trick.
Let me know what you think.

Might it be useful to have a short tutorial on retrieving parameters from an observed phase curve using something like emcee? If so, happy to make a relevant PR.
Thanks for a great package!
I have installed and can successfully import the module. But I get error on the first next line: spider_params = sp.ModelParams(brightness_model="zhang").
I work with the Zhang model.
Can i add reflection term with
Ref = ARef*(1.0+np.cos(2.np.pi(time/p)+np.pi))
to the zhang model to reach amplitude of reflection and albedo?
Thank you
Hi again,
I'm attempting to provide spiderman with a bandpass filter - but when I set spider_params.filter = 'filter.txt'
and attempt to run, I get this traceback:
Traceback (most recent call last):

raise ValueError("A value in x_new is above the interpolation "
ValueError: A value in x_new is above the interpolation range.
So the filter gets set, but it looks like the grid is trying to go over the filter interpolation range.
A fix or a suggestion would be appreciated, thanks!
Hi there!
I'm experiencing a problem trying to import SPIDERMAN
. After a successful installation and following the Quickstart example, I immediately run in to trouble trying to import spiderman:

Hence, two problems seems so arise
Regarding the first issue, I tried to install SPIDERMAN
both with pip and directly from github, but unfortunately with the same outcome. As an extra note I have functional BATMAN
installation under Python 3.8.10.
Thanks for your help!

Presently, Spiderman doesn't allow users to import brightness maps on a healpix grid which would be a super useful feature (likely requiring healpy as a dependency). As of right now I need to convert my healpix grids to spherical harmonics which loses a lot of information, and then spiderman converts those to the concentric-circle grid. If spiderman calculates the latitude-longitude grid somewhere, one could just do an interpolation between the nearest healpy coordinates. spiderman.format_grid()
currently does not accept healpix grids as they are not rectangular in latitude-longitude
Hi there,
I ran into a problem when going through the Quickstart example in the documentation. When it came to this line,
lc = spider_params.lightcurve(t)
I receive this error:
Traceback (most recent call last):

When importing spiderman I also received this note, which might be of relevence?:

Help would be appreciated, thanks!
