Another issue to contend with when trying to compare the results: putting the HLA results on the same WCS as the HAP results (HSC vs GAIA2?). This becomes critical to...

Another complication comes from the fact that HLA uses a plate-scale of 0.09(?!?) arcsec/pix for their WFC3/IR products, compared to the HAP 0.128 arcsec/pix. This makes it impossible to do...

If this is to be used as a verification criteria, it would be helpful to have some initial limit that can be used to flag whether or not there is...

This seems to make perfect sense to me. Weights are hard-coded in drizzlepac to be provided under all circumstances (see lines 898-905 in `drizzlepac\adrizzle.py`) and provide the exptime or IVM...

Cross-matching problems does not, by itself, introduce the linear residuals in Y vs DY for each chip. Using a short exposure as the reference, these systematics were introduced to all...

A good test case would be visit ib4103, specifically hst_11671_03_wfc3_ir_total_ib4103_drz.fits. The HAP product identifies a larger fraction of 'real' sources (based on visual/manual inspection) than the HLA catalog. However, all...

@mcara Unfortunately, I have been unable to reproduce the problem. I will need to work with you to understand how this error appears.
