Thanks. My interest for this in-memory reading isn't urgent, but I just wanted to check if I was missing some pre-existing mem:// like trick to make it work analogous to...

Rather than defining a new extension for the mask, how about continuing to use `TNULLn` for the mask (as defined by the FITS standard) and then use a new keyword...

Please be very wary of inventing non-standard FITS usage that would cause the table to be interpreted differently by non-astropy readers in other languages (or fitsio for that matter). I...

Hi. At first I thought this would be due to NaN or Inf values in one of the vectors (x, cw, or c), but I haven't been able to reproduce...

Glad it worked out. You are the second user who has been confused by the cryptic effect of inputs with all weights=0. I should probably add a check at the...

Great. Glad to hear that it is getting use beyond astrophysics. Stephen On Feb 20, 2014, at 7:17, petitvic [email protected] wrote: > The check would be good for new users...

The code would need to be updated in several places to have the calculation stay in float32 if the inputs are float32, e.g. line 204: ```python mx = np.zeros(self.data.shape) ```...

`weights` and `data` should both be arrays with shape `(num_observations, num_variables)`. `weights[i,j]` indicates what weight should be applied to `data[i,j]` when calculating the PCA. If observation `i` variable `j` is...

Documenting some thoughts as followup from the spectro workshop hackfest last week — IIUC @kelle identified that the problem with tabular-fits dropping the metadata when writing + reading was that...
