Scale:
If you provide an estimate of the size of your field, our search will be much faster. Most digital-camera images are at least 10 degrees wide; most professional-grade telescopes are narrower than 2 degrees.
|
{{ form.scale_preset }}
Units: {{ form.scale_units }}
{{ form.scale_type }}
Lower bound: {{ form.scale_lower }}{{ form.scale_lower.errors }}
Upper bound: {{ form.scale_upper }}{{ form.scale_upper.errors }}
Estimate: {{ form.scale_est }}{{ form.scale_est.errors }}
Error: {{ form.scale_err }}% {{ form.scale_err.errors }}
|
Parity:
Flipping an image reverses its "parity". If you point a digital camera at the sky and submit the JPEG, it probably has negative parity. If you have a FITS image, it probably has positive parity. Selecting the right parity will make the solving process run faster, but if in doubt just try both.

Star Positional Error:
When we find a matching "landmark", we check to see how many of the stars in your field match up with stars we know about. To do this, we need to know how much a star in your field could have moved from where it should be.
|
{{ form.positional_error }} pixels {{ form.positional_error.errors }}
|
Limits:
In order to narrow down our search, you can supply a field center along with a radius. We will only search in indexes which fall within this area.
|
RA: | {{ form.center_ra }} degrees {{ form.center_ra.errors }} |
Dec: | {{ form.center_dec }} degrees {{ form.center_dec.errors }} |
Radius: | {{ form.radius }} degrees {{ form.radius.errors }} |
|
Tweak:
By default we try to compute a SIP polynomial distortion correction with order 2.
You can disable this by changing the order to 0, or change the polynomial order.
|
Order: {{ form.tweak_order }} {{ form.tweak_order.errors }}
|
CRPIX center:
By default the reference point (CRPIX) of the WCS we compute can be anywhere
in your image, but often it's convenient to force it to be the center of the image.
|
{{ form.crpix_center }} CRPIX in center {{ form.crpix_center.errors }}
|
Downsample:
We can downsample your image by a given factor before performing the source extraction.
|
{{ form.downsample_factor }} (factor) {{ form.downsample_factor.errors }}
|
Invert:
Set this if your image is black-on-white (inverted) rather than white-on-black.
|
{{ form.invert }} Invert image {{ form.invert.errors }}
|
SourceExtractor:
We can detect stars using
SExtractor,
or our own built-in star detector "simplexy". If the built-in one fails,
give this a try.
|
{{ form.use_sextractor }} use SExtractor {{ form.use_sextractor.errors }}
